This paper presents a classic missile-type parallel-approach guidance law for fixed-wing UAVs in coordinated formation flight. The key idea of the proposed guidance law is to drive each follower to follow the virtual target point. Considering the turning ability of each follower, the formation form adopts the semi-perfect rigid form, which does not require the vehicle positions form a rigid formation, and the orientations keep consensus. According to the mission characteristics of the follower following a leader and the leader following a route, three guidance laws for straight, turning, and circling flight are designed. A series of experiments demonstrate the proposed guidance law’s improved response and maneuvering stability. The results of hardware-in-the-loop simulations and real flight tests prove that the proposed guidance law satisfies the practical UAV formation flight control demands.

Migratory birds have the ability to save energy during flight by arranging themselves in a V-formation. This arrangement enables an increase in the overall efficiency of the group because the wake vortices shed by each of the birds provide additional lift and thrust to every member. Therefore, the aerodynamic advantages of such a flight arrangement can be exploited in the design process of micro air vehicles. One significant difference when comparing the anatomy of birds to the design of most micro air vehicles is that bird wings are not completely rigid. Birds have the ability to actively morph their wings during the flapping cycle. Given these aspects of avian flight, the objective of this work is to incorporate active bending and torsion into multiple pairs of flapping wings arranged in a V-formation and to investigate their aerodynamic behavior using the unsteady vortex lattice method. To do so, the first two bending and torsional mode shapes of a cantilever beam are considered and the aerodynamic characteristics of morphed wings for a range of V-formation angles, while changing the group size in order to determine the optimal configuration that results in maximum propulsive efficiency, are examined. The aerodynamic simulator incorporating the prescribed morphing is qualitatively verified using experimental data taken from trained kestrel flights. The simulation results demonstrate that coupled bending and twisting of the first mode shape yields the highest propulsive efficiency over a range of formation angles. Furthermore, the optimal configuration in terms of propulsive efficiency is found to be a five-body V-formation incorporating coupled bending and twisting of the first mode at a formation angle of 140 degrees. These results indicate the potential improvement in the aerodynamic performance of the formation flight when introducing active morphing and bioinspiration.

This survey deals with the problem of the group motion of spacecraft, which is rapidly developing and relevant for many applications, in terms of developing the onboard control algorithms to ensure the fulfillment of a given mission. The paper provides a comprehensive overview of spacecraft formation flight control. The bibliography is divided into three main sections: the multiple-input–multiple-output approach, in which the formation is treated as a single entity with multiple inputs and multiple outputs; the leader–follower formation, in which individual spacecraft controllers are linked hierarchically; and a virtual structure formation, in which spacecraft are treated as rigid bodies embedded in a common virtual rigid body. This survey expands a 2004 survey and updates it with recent results.

AbstractUnmanned aircraft used as high-altitude platform system has been studied in research and industry as alternative technologies to satellites. Regarding actual operation and flight performance of such systems, multibody aircraft seems to be a promising aircraft configuration. In terms of flight dynamics, this aircraft strongly differs from classical rigid-body and flexible aircraft, because a strong interference between flight mechanic and formation modes occurs. For unmanned operation in the stratosphere, flight control laws are required. While control theory generally provides a number of approaches, the specific flight physics characteristics can be only partially considered. This paper addresses a flight control law approach based on a physically exact target model of the multibody aircraft dynamics rather than conventionally considering the system dynamics only. In the target model, hypothetical spring and damping elements at the joints are included into the equations of motion to transfer the configuration of a highly flexible multibody aircraft into one similar to a classical rigid-body aircraft. The differences between both types of aircraft are reflected in the eigenvalues and eigenvectors. Using the eigenstructure assignment, the desired damping and stiffness are established by the inner-loop flight control law. In contrast to other methods, this procedure allows a straightforward control law design for a multibody aircraft based on a physical reference model.

Pose measurement is a necessary technology for UAV navigation. Accurate pose measurement is the most important guarantee for a UAV stable flight. UAV pose measurement methods mostly use image matching with aircraft models or 2D points corresponding with 3D points. These methods will lead to pose measurement errors due to inaccurate contour and key feature point extraction. In order to solve these problems, a pose measurement method based on the structural characteristics of aircraft rigid skeleton is proposed in this paper. The depth information is introduced to guide and label the 2D feature points to eliminate the feature mismatch and segment the region. The space points obtained from the marked feature points fit the space linear equation of the rigid skeleton, and the UAV attitude is calculated by combining with the geometric model. This method does not need cooperative identification of the aircraft model, and can stably measure the position and attitude of short-range UAV in various environments. The effectiveness and reliability of the proposed method are verified by experiments on a visual simulation platform. The method proposed can prevent aircraft collision and ensure the safety of UAV navigation in autonomous refueling or formation flight.

To ensure the stability of flight, the butterfly needs to flap its wings and simultaneously move its main body to achieve all kinds of flying motion, such as taking off, hovering, or reverse flight. The high-speed camera is used to record the swing of the abdomen, the movement of the wings, and the pitch angle of the body for butterflies during their free flight; the comprehensive biokinetic observations show that the butterfly’s wings and body are coupled in various flight states. The swing of the abdomen and the flap of the fore wing affect the pitch motion significantly. For theoretical analysis of the butterfly flight, a three-dimensional multi-rigid butterfly model based on real butterfly dimension is established, and the aerodynamic of the butterfly flight is simulated and analyzed via computational fluid dynamics methods to obtain an optimal kinematic model of butterfly forward flight. Moreover, the formation and development of three-dimensional vortex structures in the forward flight are also presented. The detailed structures of vortices and their dynamic behavior show that the wing’s flap and the abdominal swing play a key role in reorienting and correcting the “clap and peel” mechanism, and the force generation mechanisms are evaluated. The research indicates that longitudinal flight performance is mainly related to the kinematic parameters of the wing and body, and it can lead to the development of butterfly-inspired flapping wing air vehicles.

Abstract Implementations of multi-UAV systems can be divided mainly into two different approaches, centralised system that synchronises positions of each vehicle by a ground station and an autonomous system based on decentralised control, which offers more flexibility and independence. Decentralisation of multi-UAV control entails the need for information sharing between all vehicles, what in some cases could be problematic due to a significant amount of data to be sent over the wireless network. To improve the reliability and the throughput of information sharing inside the formation of UAVs, this paper proposes an approach that combines virtual structure with a leader and two flocking behaviours. Each UAV has assigned different virtual migration point referenced to the leader's position which is simultaneously the origin of a formation reference frame. All migration points create together a virtual rigid structure. Each vehicle uses local behaviours of cohesion and repulsion respectively, to track its own assigned point in the structure and to avoid a collision with the previous UAV in the structure. To calculate parameters of local behaviours, each UAV should know position and attitude of the leader to define the formation reference frame and also the actual position of the previous UAV in the structure. Hence, information sharing can be based on a chain of local peer-to-peer communication between two consecutive vehicles in the structure. In such solution, the information about the leader could be sequentially transmitted from one UAV to another. Numerical simulations were prepared and carried out to verify the effectiveness of the presented approach. Trajectories recorded during those simulations show collective, coherence and collision-free flights of the formation created with five UAVs.

Dragonfly wings are known as biological composites with high morphological complexity. They mainly consist of a network of rigid veins and flexible membranes, and enable insects to perform various flight manoeuvres. Although several studies have been done on the aerodynamic performance of Odonata wings and the mechanisms involved in their deformations, little is known about the influence of vein joints on the passive deformability of the wings in flight. In this article, we present the first three-dimensional finite-element models of five different vein joint combinations observed in Odonata wings. The results from the analysis of the models subjected to uniform pressures on their dorsal and ventral surfaces indicate the influence of spike-associated vein joints on the dorsoventral asymmetry of wing deformation. Our study also supports the idea that a single vein joint may result in different angular deformations when it is surrounded by different joint types. The developed numerical models also enabled us to simulate the camber formation and stress distribution in the models. The computational data further provide deeper insights into the functional role of resilin patches and spikes in vein joint structures. This study might help to more realistically model the complex structure of insect wings in order to design more efficient bioinspired micro-air vehicles in future.

AbstractWing deformation is observed during the flight of some insect species; however, the effect of these distorted wing shapes on the leading edge vortex (LEV) is not well understood. In this study, we investigate the effect of one of these deformation parameters, (rigid) wing camber, on the flow structures and aerodynamic forces for insect-like wings, using a numerical model of an altered fruit fly wing revolving at a constant angular velocity. Both positive and negative camber was investigated at Reynolds numbers of 120 and 1500, along with the chordwise location of maximum camber. It was found that negatively cambered wings produce very similar LEV structures to non-cambered wings at both Reynolds numbers, but high positive camber resulted in the formation of multiple streamwise vortices at the higher Reynolds number, which disrupt the development of the main LEV. Despite this, positively cambered wings were found to produce higher lift to drag ratios than flat or negatively cambered wings. It was determined that a region of low pressure near the wing’s leading edge, combined with the curvature of the wing’s upper surface in this region, resulted in a vertical tilting of the net force vector for positively cambered wings, which explains how insects can benefit from wing camber.

SummaryPosition-tracking problems in the structures of rigid formations of nonholonomic mobile robots, such as fixed-wing unmanned aerial vehicle (UAVs), must reconcile tracking precision and flight stability, which usually exclude each other due to nonholonomic motion constraints. Therefore, a position-tracking control that is based on distance and position displacement, defined as inputs of control loops, requires the application of dead zones around target positions, which are the points of instability. For this reason, the control becomes sensitive to any external disturbance causing oscillations of control signals and so it becomes difficult to maintain a zero value of position displacement over a long time horizon. Thus, we propose an approach based on the adaptive mechanism of an asymmetrical local artificial potential field, which is defined by a local frame of reference whose origin is located in the tracked position of a UAV in the formation frame. It couples controls of both airspeed and heading angle into a nonlinear potential function of relative position and orientation with respect to the tracked position and adapts it according to heading rate of the leader. The function splits the area around the tracked position longitudinally into two zones of acceleration and deceleration; therefore, velocity vectors are longer (higher airspeed) only when a UAV is behind the tracked position and shorter (lower airspeed) when it is ahead. The area is laterally symmetrical, and orientations of velocity vectors align asymptotically to the longitudinal direction accordingly with the decrease in the lateral error. Finally, velocity vectors are rotated proportionally to the heading rate of the leader, which improves the tracking precision during turns. If we assumed that a UAV’s tracked position is in motion, it could easily be proven that the position control based on the adaptive asymmetrical potential function becomes asymptotically stable in the tracked position. Numerical simulation verifies this thesis and presents more precise and stable position tracking due to the adaptation mechanism.

Within the framework of the methodological support being developed for the planning and management of the fleet of a small shipping company, the task of synthesizing a management system has been solved. The structure and parameters of the system are determined based on the specified requirements for the conditions of its operation, as well as ways to ensure the goals of the functioning of the fleet management system of a small shipping company. The concept of a small, medium or large shipping company is defined by the number of vessels under operational management. It is noted that due to the variability of the economic situation in the transportation market in modern market conditions, permanent "rigid" connections between the elements of the transport system are not formed and the problem of coordinating the work of these elements exists only at the level of operational planning and regulation for small shipping companies. Therefore, it is necessary and sufficient to limit the system under study to the framework of flight planning. The fleet management system at this level in trump shipping traditionally consists of two consecutive subprocesses: the formation of vessel traffic patterns and the assignment of specific vessels to these schemes. The main result of the study is that a new management system structure was formed on the basis of a system analysis of processes in the conditions of working with a small fleet and identified addition-al tasks and requirements for the system. Distinctive features of the new structure from the prototype: the process of arranging transport vessels has been replaced by the process of determining the optimal composition of the leased fleet; two auxiliary subprocesses have been added to manage additional operations if necessary to unload cargo on an unequipped shore.

Candida sp. treatment has become a challenge due to the formation of biofilms which favor resistance to conventional antifungals, making the search for new compounds necessary. The objective of this study was to identify the composition of the Licania rigida Benth. leaf ethanolic extract and to verify its antifungal activity against Candida sp. and its biofilms. The composition identification was performed using the ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS/MS) technique. The antifungal activity of extract and fluconazole against planktonic cells and biofilms was verified through the minimum inhibitory concentration (MIC) following biofilm induction and quantification in acrylic resin discs by reducing tetrazolic salt, with all isolates forming biofilms within 48 h. Six constituents were identified in the extract, and the compounds identified are derivatives from phenolic compounds such as flavonoids (epi) gallocatechin Dimer, epigallocatechin and gallocatechin, Myricetin-O-hexoside, Myricitrin, and Quercetin-O-rhamnoside. The extract reduced biofilm formation in some of the strains analyzed, namely C. tropicalis URM5732, C. krusei INCQS40042, and C. krusei URM6352. This reduction was also observed in the treatment with fluconazole with some of the analyzed strains. The extract showed significant antifungal and anti-biofilm activities with some of the strains tested.

Aerodynamic characteristics of badminton shuttlecock are significantly different from balls used in other sports. Shuttlecock can achieve a very high initial speed and at the same time, it can decelerate very fast. This is due to the significant aerodynamic drag it experiences during its in-flight motion. A computational fluid dynamics (CFD) analysis was carried out to understand the aerodynamics of a feathers shuttlecock approved by Badminton World Federation (BWF) for international tournaments. The aerodynamics performance of a standard shuttlecock at steady-state flight was investigated. The shuttlecock was assumed to be rigid and have no spin rotation; and velocity considered was 92 m/s. Effects of parameters such as angle of attack, α; angle of skirt, Ɵ; and angle of feathers, β; on the shuttlecock drag coefficient, Cd; were studied. It is found that smaller Ɵ leads to smaller Cd. Analysis shows that the Cd is the largest when the shuttlecock is at α = 0°. Besides that, the Cd is also influenced by β which the standard shuttlecock has fairly small Cd. Formation of feathers of the standard shuttlecock may be further twisted to the optimal value of β in order to increase its drag. As a result, Ɵ and β may be considered as design parameters in order to obtain the desired aerodynamics performance.

Conversion of forewings into hardened covers, elytra, was a ground-breaking morphological adaptation that has contributed to the extraordinary evolutionary success of beetles. Nevertheless, the knowledge of the functional aspects of these structures is still fragmentary and scattered across a large number of studies. Here, we have synthesized the presently available information on the evolution, development, modifications and biological functions of this crucial evolutionary novelty. The formation of elytra took place in the earliest evolution of Coleoptera, very likely already in the Carboniferous, and was achieved through the gradual process of progressive forewing sclerotization and the formation of inward directed epipleura and a secluded sub-elytral space. In many lineages of modern beetles, the elytra have been distinctly modified. This includes multiple surface modifications, a rigid connection or fusion of the elytra, or partial or complete reduction. Beetle elytra can be involved in a very broad spectrum of functions: mechanical protection of hind wings and body, anti-predator strategies, thermoregulation and water saving, water harvesting, flight, hind wing folding, diving and swimming, self-cleaning and burrow cleaning, phoresy of symbiotic organisms, mating and courtship, and acoustic communication. We postulate that the potential of the elytra to take over multiple tasks has enormously contributed to the unparalleled diversification of beetles.

I remember the first time I saw a dead body. I spawned just before dawn; around me engines were clattering into life, the dim silhouettes of tanks beginning to move out in a steady grinding rumble. I could dimly make out a few other people, the anonymity of their shadowy outlines belied by the names hanging over their heads in a comforting blue. Suddenly, a stream of tracers arced across the sky; explosions sounded nearby, then closer still; a tank ahead of me stopped, turned sluggishly, and fired off a couple of rounds, rocking slightly against the recoil. The radio was filled with talk of Germans in the town, but I couldn’t even see the town. I ran toward what looked like the shattered hulk of a building and dived into what I hoped was a doorway. It was already occupied by another Tommy and together we waited for it to get lighter, listening to the rattle of machine guns, the sharp ping as shells ricocheted off steel, the sickening, indescribable, but immediately recognisable sound when they didn’t. Eventually, the other soldier moved out, but I waited for the sun to peek over the nearby hills. Once I was able to see where I was going, I made straight for the command post on the edge of town, and came across a group of allied soldiers standing in a circle. In the centre of the circle lay a dead German soldier, face up. “Well I’ll be damned,” I said aloud; no one else said anything, and the body abruptly faded. I remember the first time I killed someone. I had barely got the Spit V up to 4000 feet when out of the corner of my eye I caught a glimpse of something below me. I dropped the left wing and saw a Stuka making a bee-line for the base. I made a hash of the turn, almost stalling, but he obviously had no idea I was there. I saddled-up on his six, dropping down low to avoid fire from his gunner, and opened up on him. I must have hit him at perfect convergence because he disintegrated, pieces of dismembered airframe raining down on the field below. I circled the field, putting all my concentration into making the landing that would make the kill count, then switched off the engine and sat in the cockpit for a moment, heart pounding. As you can tell, I’ve been in the wars lately. The first example is drawn from the launch of Cornered Rat Software’s WWII Online: Blitzkrieg (2001) while the second is based on a short stint playing Warbirds 3 (2002). Both games are examples of one of the most interesting recent developments in computer and video gaming: the increasing popularity and range of Massively Multiplayer Online Games (MMOGs); other notable examples of historical combat simulation MMOGs include HiTech Creations Aces High (2002) and Jaleco Entertainment’s Fighter Ace 3.5 (2002). For a variety of technical reasons, most popular multiplayer games—particularly first-person shooter (FPS) games such as Doom, Quake, and more recently Medal of Honor: Allied Assault (2002) and Return to Castle Wolfenstein (2001)—are played on player-organised servers that are usually limited to 32 or fewer players; terrain maps are small and rotated every couple of hours on average. MMOGs, by contrast, feature anywhere from hundreds to tens of thousands of players hosted on a handful of company-run servers. The shared virtual geography of these worlds is huge, extending across tens of thousands of square miles; these worlds are also persistent in that they respond dynamically to the actions of players and continue to do so while individual players are offline. As my opening anecdotes demonstrate, the experience of dealing and receiving virtual death is central to massively multiplayer simulations as it is to so many forms of computer games. Yet for an experience is that is so ubiquitous in computer games (and, some would say, even constitutes their experiential core) death is under-theorised. Mainstream culture tends to see computer and console game mayhem according to a rigid desensitisation argument: the experience of repeatedly killing other players online leads to a gradual erosion of the individual moral sense which makes players more likely to countenance killing people in the real world. Nowhere was this argument more in evidence that in the wake of the murder of fifteen students by Dylan Klebold and Eric Harris at Columbine High School in Littleton, Colorado on April 20, 1999. The discovery that the two boys were enthusiastic players of Id Software’s Doom and Quake resulted in an avalanche of hysterical news stories that charged computer games with a number of evils: eroding kids’ ability to distinguish fantasy from reality, encouraging them to imitate the actions represented in the games, and immuring them to the real-world consequences of violence. These claims were hardly new, and had in fact been directed at any number of violent popular entertainment genres over the years. What was new was the claim that the interactive nature of FPS games rendered them a form of simulated weapons training. What was also striking about the discourse surrounding the Littleton shooting was just how little the journalists covering the story knew about computer, console and arcade games. Nevertheless, their approach to the issue encouraged readers to see games as having real life analogs. Media discussion of the event also reinforced the notion of a connection with military training techniques, making extensive use of Lt. Col. (ret) David Grossman, a former Army ranger and psychologist who led the charge in claiming that games were “mass-murder simulators” (Gittrich, AA06). This controversy over the role of violent computer games in the Columbine murders is part of a larger cultural discourse that adopts the logical fallacy characteristic of moral panics: coincidence equals causation. Yet the impoverished discussion of online death and destruction is also due in no small measure to an entrenched hostility toward popular entertainment as a whole, a hostility that is evident even in the work of some academic critics who study popular culture. Andrew Darley, for example, argues that, never has the flattening of meaning or depth in the traditional aesthetic sense of these words been so pronounced as in the action-simulation genres of the computer game: here, aesthetic experience is tied directly to the purely sensational and allied to tests of physical dexterity (143). In this view, the repeated experience of death is merely a part of the overall texture of a form characterised not so much by narrative as by compulsive repetition. More generally, computer games are seen by many critics as the pernicious, paradigmatic instance of the colonisation of individual consciousness by cultural spectacle. According to this Frankfurt school-influenced critique (most frequently associated with the work of Guy Debord), spectacle serves both to mystify and pacify its audience: The more the technology opens up narrative possibilities, the less there is for the audience to do. [. . .]. When the spectacle conceals the practice of the artists who create it, it [announces]…itself as an expression of a universe beyond human volition and effort (Filewood 24). In supposedly sapping its audience’s critical faculties by bombarding them with a technological assault whose only purpose is to instantiate a deterministic worldview, spectacle is seen by its critics as exemplifying the work of capitalist ideology which teaches people not to question the world around them by establishing, in Althusser’s famous phrase, an “imaginary relationship of individuals to their real conditions of their existence” (162). The desensitisation thesis is thus part of a larger discourse that considers computer games paradoxically to be both escapist and as having real-world effects. With regard to online death, neo-Marxism meets neo-Freudianism: players are seen as hooked on the thrill not only of destroying others but also of self-destruction. Death is thus considered the terminus of all narrative possibility, and the participation of individuals in fantasy-death and mayhem is seen to lead inevitably to several kinds of cultural death: the death of “family values,” the death of community, the death of individual responsibility, and—given the characterisation of FPS games in particular as lacking in plot and characterisation—the death of storytelling. However, it is less productive to approach computer, arcade and console games as vehicles for force-feeding content with pre-determined cultural effects than it is to understand them as venues within and around which players stage a variety of theatrical performances. Thus even the bêtes noire of the mainstream media, first-person shooters, serve as vehicles for a variety of interactions ranging from the design of new sounds, graphics and levels, new “skins” for player characters, the formation of “tribes” or “clans” that fight and socialise together, and the creation of elaborate fan fictions. This idea that narrative does not simply “happen” within the immediate experience of playing the game, but is in fact produced by a dynamic interplay of interactions for which the game serves as a focus, also suggests a very different way of looking at the role of death online. Far from being the logical endpoint, the inevitable terminus of all narrative possibility, death becomes the indispensable starting point for narrative. In single-player games, for example, the existence of the simple “save game” function—differing from simply putting the game board to one side in that the save function allows the preservation of the game world in multiple temporal states—generates much of the narrative and dramatic range of computer games. Generally a player saves the game because he or she is facing an obstacle that may result in death; saving the game at that point allows the player to investigate alternatives. Thus, the ever-present possibility of death in the game world becomes the origin of all narratives based on forward investigation. In multiplayer and MMOG environments, where the players have no control over the save game state, it is nevertheless the possibility of a mode of forward projection that gives the experience its dramatic intensity. Flight simulation games in particular are notoriously difficult to master; the experience of serial death, therefore, becomes the necessary condition for honing your flying skills, trying out different tactics in a variety of combat situations, trying similar tactics in different aircraft, and so on. The experience of online death creates a powerful narrative impulse, and not only in those situations where death is serialised and guaranteed. A sizable proportion of the flight sim communities of both Warbirds and Aces High participate in specially designed scenario events that replicate a specific historical air combat event (the Battle of Britain, the Coral Sea, USAAF bomber operations in Europe, etc.) as closely as possible. What makes these scenarios so compelling for many players is that they are generally “one life” events: once the player is dead, they are out for the rest of the event and this creates an intense experience that is completely unlike flying in the everyday free-for-all arenas. The desensitisation thesis notwithstanding, there is little evidence that this narrative investment in death produces a more casual attitude toward real-life death amongst MMOG players. For example, when real-world death intrudes, simulation players often reach for the same rituals of comfort and acknowledgement that are employed offline. Recently, when an Aces High player died unexpectedly of heart failure at the age of 35, his squadron held an elaborate memorial event in his honor. Over a hundred players bailed out over an aerodrome—bailing out is the only way that a player in Aces High can acquire a virtual human body—and lined the edges of the runway as members of the dead player’s squad flew the missing man formation overhead (GrimmCAF). The insistence upon bodily presence in the context of a classic military ceremony marking irrecoverable absence suggests the way in which the connections between real and virtual worlds are experienced by players: as tensions, but also as points where identities are negotiated. This example does not seem to indicate that everyday familiarity with virtual death has dulled the players’ sensibilities to the sorrow and loss accompanying death in the real world. I began this article talking about death in simulation MMOGs for a number of reasons. In the first place, MMOGs are more commonly identified with their role-playing examples (MMORPGs) such as Ultima Online and Everquest, games that focus on virtual community-building and exploration in addition to violence and conquest. By contrast, simulation games tend to be seen as having more in common with first-person shooters like Quake, in the way in which they foreground the experience of serial death. Secondly, it is precisely the connection between simulation and death that makes games in general (as I demonstrated in relation to the media coverage of the Columbine murders) so problematic. In response, I would argue that one of the most interesting aspects of computer games recently has been the degree to which generic distinctions have been breaking down. MMORPGs, which had their roots in the Dungeons and Dragons gaming world, and the text-based world of MUDs and MOOs have since developed sophisticated third-person and even first-person representational styles to facilitate both peaceful character interactions and combat. Likewise, first-person shooters have begun to add role-playing elements (see, for example, Looking Glass Studios’ superb System Shock 2 (1999) or Lucasarts' Jedi Knight series). This trend has also been incorporated into simulation MMOGs: World War II Online includes a rudimentary set of character-tracking features, and Aces High has just announced a more ambitious expansion whose major focus will be the incorporation of role-playing elements. I feel that MMOGs in particular are all evolving towards a state that I would describe as “simulance:” simulations that, while they may be associated with a nominal representational reality, are increasingly about exploring the narrative possibilities, the mechanisms of theatrical engagement for self and community of simulation itself. Increasingly, none of the terms "simulation,” "role-playing" or indeed “game” quite captures the texture of these evolving experiences. In their complex engagement with both scripted and extemporaneous narrative, the players have more in common with period re-enactors; the immersive power of a well-designed flight simulator scenario produces a feeling in players akin to the “period rush” experienced by battlefield re-enactors, the frisson between awareness of playing a role and surrendering completely to the momentary power of its illusory reality. What troubles critics about simulations (and what also blinds them to the narrative complexity in other forms of computer games) is that they are indeed not simply examples of re-enactment —a re-staging of supposedly real events—but a generative form of narrative enactment. Computer games, particularly large-scale online games, provide a powerful set of theatrical tools with which players and player communities can help shape narratives and deepen their own narrative investment. Obviously, they are not isolated from real-world cultural factors that shape and constrain narrative possibility. However, we are starting to see the way in which the games use the idea of virtual death as the generative force for new storytelling frameworks based, in Filewood’s terms, on forward investigation. As games begin to move out of their incunabular state, they may contribute to the re-shaping of culture and consciousness, as other narrative platforms have done. Far from causing the downfall of civilisation, game-based narratives may bring with them a greater cultural awareness of simultaneous narrative possibility, of the past as sets of contingent phenomena, and a greater attention to practical, hands-on experimental problem-solving. It would be ironic, but no great surprise, if a form built around the creative possibilities inherent in serial death in fact made us more attentive to the rich alternative possibilities of living.

As Lewis Carroll’s Alice comes to the end of her journey through the looking glass world, she has also come to the end of her patience with its strange power games and arbitrations. At every stage of the adventure, she has encountered someone who wants to dictate rules and protocols, and a lesson on table manners from the Red Queen finally triggers rebellion. “I can’t stand this any more,” Alice cries, as she seizes the tablecloth and hurls the entire setting into chaos (279). Then, catching hold of the Red Queen, she gives her a good shaking, until the rigid contours of the imperious figure become fuzzy and soft. At this point, the hold of the dream dissolves and Alice, awakening on the other side of the mirror, realises she is shaking the kitten. Queens have long been associated with ideas of transformation. As Alice is duly advised when she first looks out across the chequered landscape of the looking glass world, the rules of chess decree that a pawn may become a queen if she makes it to the other side. The transformation of pawn to queen is in accord with the fairy tale convention of the unspoiled country girl who wins the heart of a prince and is crowned as his bride. This works in a dual register: on one level, it is a story of social elevation, from the lowest to the highest rank; on another, it is a magical transition, as some agent of fortune intervenes to alter the determinations of the social world. But fairy tales also present us with the antithesis and adversary of the fortune-blessed princess, in the figure of the tyrant queen who works magic to shape destiny to her own ends. The Queen and the mirror converge in the cultural imaginary, working transformations that disrupt the order of nature, invert socio-political hierarchies, and flout the laws of destiny. In “Snow White,” the powers of the wicked queen are mediated by the looking glass, which reflects and affirms her own image while also serving as a panopticon, keep the entire realm under surveillance, to pick up any signs of threat to her pre-eminence. All this turbulence in the order of things lets loose a chaotic phantasmagoria that is prime material for film and animation. Two major film versions of “Snow White” have been released in the past few years—Mirror Mirror (2012) and Snow White and the Huntsman (2012)—while Tim Burton’s animated 3D rendition of Alice in Wonderland was released in 2010. Alice through the Looking Glass (2016) and The Huntsman: Winter’s War, the 2016 prequel to Snow White and the Huntsman, continue the experiment with state-of-the-art-techniques in 3D animation and computer-generated imaging to push the visual boundaries of fantasy. Perhaps this escalating extravagance in the creation of fantasy worlds is another manifestation of the ancient lore and law of sorcery: that the magic of transformation always runs out of control, because it disrupts the all-encompassing design of an ordered world. This principle is expressed with poetic succinctness in Ursula Le Guin’s classic story A Wizard of Earthsea, when the Master Changer issues a warning to his most gifted student: But you must not change one thing, one pebble, one grain of sand, until you know what good and evil will follow on that act. The world is in balance, in Equilibrium. A wizard's power of Changing and Summoning can shake the balance of the world. It is dangerous, that power. (48)In Le Guin’s story, transformation is only dangerous if it involves material change; illusions of all kinds are ultimately harmless because they are impermanent.Illusions mediated by the mirror, however, blur the distinction Le Guin is making, for the mirror image supposedly reflects a real world. And it holds the seductive power of a projected narcissism. Seeing what we wish for is an experience that can hold us captive in a way that changes human nature, and so leads to dangerous acts with material consequences. The queen in the mirror becomes the wicked queen because she converts the world into her image, and in traditions of animation going back to Disney’s original Snow White (1937) the mirror is itself an animate being, with a spirit whose own determinations become paramount. Though there are exceptions in the annals of fairy story, powers of transformation are typically dark powers, turbulent and radically elicit. When they are mediated through the agency of the mirror, they are also the powers of narcissism and autocracy. Through a Glass DarklyIn her classic cultural history of the mirror, Sabine Melchior-Bonnet tracks a duality in the traditions of symbolism associated with it. This duality is already evident in Biblical allusions to the mirror, with references to the Bible itself as “the unstained mirror” (Proverbs 7.27) counterpointed by images of the mortal condition as one of seeing “through a glass darkly” (1 Corinthians 13.12).The first of these metaphoric conventions celebrates the crystalline purity of a reflecting surface that reveals the spiritual identity beneath the outward form of the human image. The church fathers drew on Plotinus to evoke “a whole metaphysics of light and reflection in which the visible world is the image of the invisible,” and taught that “humans become mirrors when they cleanse their souls (Melchior-Bonnet 109–10). Against such invocations of the mirror as an intermediary for the radiating presence of the divine in the mortal world, there arises an antithetical narrative, in which it is portrayed as distorting, stained, and clouded, and therefore an instrument of delusion. Narcissus becomes the prototype of the human subject led astray by the image itself, divorced from material reality. What was the mirror if not a trickster? Jean Delumeau poses this question in a preface to Melchior-Bonnet’s book (xi).Through the centuries, as Melchior-Bonnet’s study shows, these two strands are interwoven in the cultural imaginary, sometimes fused, and sometimes torn asunder. With Venetian advances in the techniques and technologies of mirror production in the late Renaissance, the mirror gained special status as a possession of pre-eminent beauty and craftsmanship, a means by which the rich and powerful could reflect back to themselves both the self-image they wanted to see, and the world in the background as a shimmering personal aura. This was an attempt to harness the numinous influence of the divinely radiant mirror in order to enhance the superiority of leading aristocrats. By the mid seventeenth century, the mirror had become an essential accessory to the royal presence. Queen Anne of Austria staged a Queen’s Ball in 1633, in a hall surrounded by mirrors and tapestries. The large, finely polished mirror panels required for this kind of display were made exclusively by craftsmen at Murano, in a process that, with its huge furnaces, its alternating phases of melting and solidifying, its mysterious applications of mercury and silver, seemed to belong to the transformational arts of alchemy. In 1664, Louis XIV began to steal unique craftsmen from Murano and bring them to France, to set up the Royal Glass and Mirror Company whose culminating achievement was the Hall of Mirrors at Versailles.The looking glass world of the palace was an arena in which courtiers and visitors engaged in the high-stakes challenge of self-fashioning. Costume, attitude, and manners were the passport to advancement. To cut a figure at court was to create an identity with national and sometimes international currency. It was through the art of self-fashioning that the many princesses of Europe, and many more young women of title and hereditary distinction, competed for the very few positions as consort to the heir of a royal house. A man might be born to be king, but a woman had to become a queen.So the girl who would be queen looks in the mirror to assess her chances. If her face is her fortune, what might she be? A deep relationship with the mirror may serve to enhance her beauty and enable her to realise her wish, but like all magical agents, the mirror also betrays anyone with the hubris to believe they are in control of it. In the Grimm’s story of “Snow White,” the Queen practises the ancient art of scrying, looking into a reflective surface to conjure images of things distant in time and place. But although the mirror affords her the seer’s visionary capacity to tell what will be, it does not give her the power to control the patterns of destiny. Driven to attempt such control, she must find other magic in order to work the changes she desires, and so she experiments with spells of self-transformation. Here the doubleness of the mirror plays out across every plane of human perception: visual, ethical, metaphysical, psychological. A dynamic of inherent contradiction betrays the figure who tries to engage the mirror as a servant. Disney’s original 1937 cartoon shows the vain Queen brewing an alchemical potion that changes her into the very opposite of all she has sought to become: an ugly, ill-dressed, and impoverished old woman. This is the figure who can win and betray trust from the unspoiled princess to whom the arts of self-fashioning are unknown. In Tarsem Singh’s film Mirror Mirror, the Queen actually has two mirrors. One is a large crystal egg that reflects back a phantasmagoria of palace scenes; the other, installed in a primitive hut on an island across the lake, is a simple looking glass that shows her as she really is. Snow White and the Huntsman portrays the mirror as a golden apparition, cloaked and faceless, that materialises from within the frame to stand before her. This is not her reflection, but with every encounter, she takes on more of its dark energies, until, in another kind of reversal, she becomes its image and agent in the wider world. As Ursula Le Guin’s sage teaches the young magician, magic has its secret economies. You pay for what you get, and the changes wrought will come back at you in ways you would never have foreseen. The practice of scrying inevitably leads the would-be clairvoyant into deeper levels of obscurity, until the whole world turns against the seer in a sequence of manifestations entirely contrary to his or her framework of expectation. Ultimately, the lesson of the mirror is that living in obscurity is a defining aspect of the human condition. Jorge Luis Borges, the blind writer whose work exhibits a life-long obsession with mirrors, surveys a range of interpretations and speculations surrounding the phrase “through a glass darkly,” and quotes this statement from Leon Bloy: “There is no human being on earth capable of declaring with certitude who he is. No one knows what he has come into this world to do . . . or what his real name is, his enduring Name in the register of Light” (212).The mirror will never really tell you who you are. Indeed, its effects may be quite the contrary, as Alice discovers when, within a couple of moves on the looking glass chessboard, she finds herself entering the wood of no names. Throughout her adventures she is repeatedly interrogated about who or what she is, and can give no satisfactory answer. The looking glass has turned her into an estranged creature, as bizarre a species as any of those she encounters in its landscapes.Furies“The furies are at home in the mirror,” wrote R. S. Thomas in his poem “Reflections” (265). They are the human image gone haywire, the frightening other of what we hope to see in our reflection. As the mirror is joined by technologies of the moving image in twentieth-century evolutions of the myth, the furies have been given a new lease of life on the cinema screen. In Disney’s 1937 cartoon of Snow White, the mirror itself has the face of a fury, which emerges from a pool of blackness like a death’s head before bringing the Queen’s own face into focus. As its vision comes into conflict with hers, threatening the dissolution of the world over which she presides, the mirror’s face erupts into fire.Computer-generated imaging enables an expansive response to the challenges of visualisation associated with the original furies of classical mythology. The Erinyes are unstable forms, arising from liquid (blood) to become semi-materialised in human guise, always ready to disintegrate again. They are the original undead, hovering between mortal embodiment and cadaverous decay. Tearing across the landscape as a flock of birds, a swarm of insects, or a mass of storm clouds, they gather into themselves tremendous energies of speed and motion. The 2012 film Snow White and the Huntsman, directed by Rupert Sanders, gives us the strongest contemporary realisation of the archaic fury. Queen Ravenna, played by Charlize Theron, is a virtuoso of the macabre, costumed in a range of metallic exoskeletons and a cloak of raven’s feathers, with a raised collar that forms two great black wings either side of her head. Powers of dematerialisation and rematerialisation are central to her repertoire. She undergoes spectacular metamorphosis into a mass of shrieking birds; from the walls around her she conjures phantom soldiers that splinter into shards of black crystal when struck by enemy swords. As she dies at the foot of the steps leading up to the great golden disc of her mirror, her face rapidly takes on the great age she has disguised by vampiric practices.Helena Bonham Carter as the Red Queen in Burton’s Alice in Wonderland is a figure midway between Disney’s fairy tale spectre and the fully cinematic register of Theron’s Ravenna. Bonham Carter’s Queen, with her accentuated head and pantomime mask of a face, retains the boundaries of form. She also presides over a court whose visual structures express the rigidities of a tyrannical regime. Thus she is no shape-shifter, but energies of the fury are expressed in her voice, which rings out across the presence chamber of the palace and reverberates throughout the kingdom with its calls for blood. Alice through the Looking Glass, James Bobin’s 2016 sequel, puts her at the centre of a vast destructive force field. Alice passes through the mirror to encounter the Lord of Time, whose eternal rule must be broken in order to break the power of the murdering Queen; Alice then opens a door and tumbles in free-fall out into nothingness. The place where she lands is a world not of daydream but of nightmare, where everything will soon be on fire, as the two sides in the chess game advance towards each other for the last battle. This inflation of the Red Queen’s macabre aura and impact is quite contrary to what Lewis Carroll had in mind for his own sequel. In some notes about the stage adaptation of the Alice stories, he makes a painstaking distinction between the characters of the queen in his two stories.I pictured to myself the Queen of Hearts as a sort of embodiment of ungovernable passion—a blind and aimless Fury. The Red Queen I pictured as a Fury, but of another type; her passion must be cold and calm—she must be formal and strict, yet not unkindly; pedantic to the 10th degree, the concentrated essence of governesses. (86)Yet there is clearly a temptation to erase this distinction in dramatisations of Alice’s adventures. Perhaps the Red Queen as a ‘not unkindly’ governess is too restrained a persona for the psychodynamic mythos surrounding the queen in the mirror. The image itself demands more than Carroll wants to accord, and the original Tenniel illustrations give a distinctly sinister look to the stern chess queen. In their very first encounter, the Red Queen contradicts every observation Alice makes, confounds the child’s sensory orientation by inverting the rules of time and motion, and assigns her the role of pawn in the game. Kafka or Orwell would not have been at all relaxed about an authority figure who practises mind control, language management, and identity reassignment. But here Carroll offers a brilliant modernisation of the fairy story tradition. Under the governance of the autocratic queen, wonderland and the looking glass world are places in which the laws of science, logic, and language are overturned, to be replaced by the rules of the queen’s games: cards and croquet in the wonderland, and chess in the looking glass world. Alice, as a well-schooled Victorian child, knows something of these games. She has enough common sense to be aware of how the laws of gravity and time and motion are supposed to work, and if she boasts of being able to believe six impossible things before breakfast, this signifies that she has enough logic to understand the limits of possibility. She would also have been taught about species and varieties and encouraged to make her own collections of natural forms. But the anarchy of the queen’s world extends into the domain of biology: species of all kinds can talk, bodies dissolve or change size, and transmutations occur instantaneously. Thus the world-warping energies of the Erinyes are re-imagined in an absurdist’s challenge to the scientist’s universe and the logician’s mentality.Carroll’s instinct to tame the furies is in accord with the overall tone and milieu of his stories, which are works of quirky charm rather than tales of terror, but his two queens are threatening enough to enable him to build the narrative to a dramatic climax. For film-makers and animators, though, it is the queen who provides the dramatic energy and presence. There is an over-riding temptation to let loose the pandemonium of the original Erinyes, exploiting their visual terror and their classical association with metamorphosis. FashioningThere is some sociological background to the coupling of the queen and the mirror in fairy story. In reality, the mirror might assist an aspiring princess to become queen by enchanting the prince who was heir to the throne, but what was the role of the looking glass once she was crowned? Historically, the self-imaging of the queen has intense and nervous resonances, and these can be traced back to Elizabeth I, whose elaborate persona was fraught with newly interpreted symbolism. Her portraits were her mirrors, and they reflect a figure in whom the qualities of radiance associated with divinity were transferred to the human monarch. Elizabeth developed the art of dressing herself in wearable light. If she lacked for a halo, she made up for it with the extravagant radiata of her ruffs and the wreaths of pearls around her head. Pearls in mediaeval poetry carried the mystique of a luminous microcosm, but they were also mirrors in themselves, each one a miniature reflecting globe. The Ditchely portrait of 1592 shows her standing as a colossus between heaven and earth, with the changing planetary light cycle as background. This is a queen who rules the world through the mediation of her own created image. It is an inevitable step from here to a corresponding intervention in the arrangement of the world at large, which involves the armies and armadas that form the backdrop to her other great portraits. And on the home front, a regime of terror focused on regular public decapitations and other grisly executions completes the strategy to remaking the world according to her will. Renowned costume designer Eiko Ishioka created an aesthetic for Mirror Mirror that combines elements of court fashion from the Elizabethan era and the French ancien régime, with allusions to Versailles. Formality and mannerism are the keynotes for the palace scenes. Julia Roberts as the Queen wears a succession of vast dresses that are in defiance of human scale and proportion. Their width at the hem is twice her height, and 100,000 Svarovski crystals were used for their embellishment. For the masked ball scene, she makes her entry as a scarlet peacock with a high arching ruff of pure white feathers. She amuses herself by arranging her courtiers as pieces on a chess-board. So stiffly attired they can barely move more than a square at a time, and with hats surmounted by precariously balanced ships, they are a mock armada from which the Queen may sink individual vessels on a whim, by ordering a fatal move. Snow White and the Huntsman takes a very different approach to extreme fashioning. Designer Colleen Atwood suggests the shape-shifter in the Queen’s costumes, incorporating materials evoking a range of species: reptile scales, fluorescent beetle wings from Thailand, and miniature bird skulls. There is an obvious homage here to the great fashion designer Alexander McQueen, whose hallmark was a fascination with the organic costuming of creatures in feathers, fur, wool, scales, shells, and fronds. Birds were everywhere in McQueen’s work. His 2006 show Widows of Culloden featured a range of headdresses that made the models look as if they had just walked through a flock of birds in full flight. The creatures were perched on their heads with outstretched wings askance across the models’ faces, obscuring their field of vision. As avatars from the spirit realm, birds are emblems of otherness, and associated with metempsychosis, the transmigration of souls. These resonances give a potent mythological aura to Theron’s Queen of the dark arts.Mirror Mirror and Snow White and the Huntsman accordingly present strikingly contrasted versions of self-fashioning. In Mirror Mirror we have an approach driven by traditions of aristocratic narcissism and courtly persona, in which form is both rigid and extreme. The Queen herself, far from being a shape-shifter, is a prisoner of the massive and rigid architecture that is her costume. Snow White and the Huntsman gives us a more profoundly magical interpretation, where form is radically unstable, infused with strange energies that may at any moment manifest themselves through violent transformation.Atwood was also costume designer for Burton’s Alice in Wonderland, where an invented framing story foregrounds the issue of fashioning as social control. Alice in this version is a young woman, being led by her mother to a garden party where a staged marriage proposal is to take place. Alice, as the social underling in the match, is simply expected to accept the honour. Instead, she escapes the scene and disappears down a rabbit hole to return to the wonderland of her childhood. In a nice comedic touch, her episodes of shrinking and growing involve an embarrassing separation from her clothes, so divesting her also of the demure image of the Victorian maiden. Atwood provides her with a range of fantasy party dresses that express the free spirit of a world that is her refuge from adult conformity.Alice gets to escape the straitjacket of social formation in Carroll’s original stories by overthrowing the queen’s game, and with it her micro-management of image and behaviour. There are other respects, though, in which Alice’s adventures are a form of social and moral fashioning. Her opening reprimand to the kitten includes some telling details about her own propensities. She once frightened a deaf old nurse by shouting suddenly in her ear, “Do let’s pretend that I’m a hungry hyaena and you’re a bone!” (147). Playing kings and queens is one of little Alice’s favourite games, and there is more than a touch of the Red Queen in the way she bosses and manages the kitten. It is easy to laud her impertinence in the face of the tyrannical characters she meets in her fantasies, but does she risk becoming just like them?As a story of moral self-fashioning, Alice through the Looking Glass cuts both ways. It is at once a critique of the Victorian social straitjacket, and a child’s fable about self-improvement. To be accorded the status of queen and with it the freedom of the board is also to be invested with responsibilities. If the human girl is the queen of species, how will she measure up? The published version of the story excludes an episode known to editors as “The Wasp in a Wig,” an encounter that takes place as Alice reaches the last ditch before the square upon which she will be crowned. She is about to jump the stream when she hears a sigh from woods behind her. Someone here is very unhappy, and she reasons with herself about whether there is any point in stopping to help. Once she has made the leap, there will be no going back, but she is reluctant to delay the move, as she is “very anxious to be a Queen” (309). The sigh comes from an aged creature in the shape of a wasp, who is sitting in the cold wind, grumbling to himself. Her kind enquiries are greeted with a succession of waspish retorts, but she persists and does not leave until she has cheered him up. The few minutes devoted “to making the poor old creature comfortable,” she tells herself, have been well spent.Read in isolation, the episode is trite and interferes with the momentum of the story. Carroll abandoned it on the advice of his illustrator John Tenniel, who wrote to say it didn’t interest him in the least (297). There is interest of another kind in Carroll’s instinct to arrest Alice’s momentum at that critical stage, with what amounts to a small morality tale, but Tenniel’s instinct was surely right. The mirror as a social object is surrounded by traditions of self-fashioning that are governed by various modes of conformity: moral, aesthetic, political. Traditions of myth and fantasy allow wider imaginative scope for the role of the mirror, and by association, for inventive speculation about human transformation in a world prone to extraordinary upheavals.

Al Gore brought climate change into … our living rooms. … The 2008 oil price hikes [and the global financial crisis] awakened the world to potential economic hardship in a rapidly urbanising world where the petrol-driven automobile is still king. (Mouritz 47) Six hundred million cars (Urry, “Climate Change” 265) traverse the world’s roads, or sit idly in garages and clogging city streets. The West’s economic progress has been built in part around the success of the automotive industry, where the private car rules the spaces and rhythms of daily life. The problem of “automobile dependence” (Newman and Kenworthy) is often cited as one of the biggest challenges facing countries attempting to combat anthropogenic climate change. Sociologist John Urry has claimed that automobility is an “entire culture” that has re-defined movement in the contemporary world (Urry Mobilities 133). As such, it is the single most significant environmental challenge “because of the intensity of resource use, the production of pollutants and the dominant culture which sustains the major discourses of what constitutes the good life” (Urry Sociology 57-8). Climate change has forced a re-thinking of not only how we produce and dispose of cars, but also how we use them. What might a society not dominated by the private, petrol-driven car look like? Some of the pre-eminent writers on climate change futures, such as Gwynne Dyer, James Lovelock and John Urry, discuss one possibility that might emerge when oil becomes scarce: societies will descend into civil chaos, “a Hobbesian war of all against all” where “regional warlordism” and the most brutish, barbaric aspects of human nature come to the fore (Urry, “Climate Change” 261). Discussing a post-car society, John Urry also proffers another scenario in his “sociologies of the future:” an Orwellian “digital panopticon” in which other modes of transport, far more suited to a networked society, might emerge on a large scale and, in the long run, “might tip the system” into post-car one before it is too late (Urry, “Climate Change” 261). Amongst the many options he discusses is car sharing. Since its introduction in Germany more than 30 years ago, most of the critical literature has been devoted to the planning, environmental and business innovation aspects of car sharing; however very little has been written on its cultural dimensions. This paper analyses this small but developing trend in many Western countries, but more specifically its emergence in Sydney. The convergence of climate change discourse with that of the global financial crisis has resulted in a focus in the mainstream media, over the last few months, on technologies and practices that might save us money and also help the environment. For instance, a Channel 10 News story in May 2009 focused on the boom in car sharing in Sydney (see: http://www.youtube.com/watch? v=EPTT8vYVXro). Car sharing is an adaptive technology that doesn’t do away with the car altogether, but rather transforms the ways in which cars are used, thought about and promoted. I argue that car sharing provides a challenge to the dominant consumerist model of the privately owned car that has sustained capitalist structures for at least the last 50 years. In addition, through looking at some marketing and promotion tactics of car sharing in Australia, I examine some emerging car sharing subjectivities that both extend and subvert the long-established discourses of the automobile’s flexibility and autonomy to tempt monogamous car buyers into becoming philandering car sharers. Much literature has emerged over the last decade devoted to the ubiquitous phenomenon of automobility. “The car is the literal ‘iron cage’ of modernity, motorised, moving and domestic,” claims Urry (“Connections” 28). Over the course of twentieth century, automobility became “the dominant form of daily movement over much of the planet (dominating even those who do not move by cars)” (Paterson 132). Underpinning Urry’s prolific production of literature is his concept of automobility. This he defines as a complex system of “intersecting assemblages” that is not only about driving cars but the nexus between “production, consumption, machinic complexes, mobility, culture and environmental resource use” (Urry, “Connections” 28). In addition, Matthew Paterson, in his Automobile Politics, asserts that “automobility” should be viewed as everything that makes driving around in a car possible: highways, parking structures and traffic rules (87). While the private car seems an inevitable outcome of a capitalistic, individualistic modern society, much work has gone into the process of naturalising a dominant notion of automobility on drivers’ horizons. Through art, literature, popular music and brand advertising, the car has long been associated with seductive forms of identity, and societies have been built around a hegemonic culture of car ownership and driving as the pre-eminent, modern mode of self-expression. And more than 50 years of a popular Hollywood film genre—road movies—has been devoted to glorifying the car as total freedom, or in its more nihilistic version, “freedom on the road to nowhere” (Corrigan). As Paterson claims, “autonomous mobility of car driving is socially produced … by a range of interventions that have made it possible” (18). One of the main reasons automobility has been so successful, he claims, is through its ability to reproduce capitalist society. It provided a commodity around which a whole set of symbols, images and discourses could be constructed which served to effectively legitimise capitalist society. (30) Once the process is locked-in, it then becomes difficult to reverse as billions of agents have adapted to it and built their lives around “automobility’s strange mixture of co-ercion and flexibility” (Urry, “Climate Change” 266). The Decline of the Car Globally, the greatest recent rupture in the automobile’s meta-narrative of success came about in October 2008 when three CEOs from the major US car firms (General Motors, Ford and Chrysler) begged the United States Senate for emergency loan funds to avoid going bankrupt. To put the economic significance of this into context, Emma Rothschild notes “when the listing of the ‘Fortune 500’ began in 1955, General Motors was the largest American corporation, and it was one of the three largest, measured in revenues, every year until 2007” (Rothschilds, “Can we transform”). Curiously, instead of focusing on the death of the car (industry), as we know it, that this scenario might inevitably herald, much of the media attention focused on the hypocrisy and environmental hubris of the fact that all the CEOs had flown in private luxury jets to Washington. “Couldn’t they have at least jet-pooled?” complained one Democrat Senator (Wutkowski). In their next visit to Washington, most of them drove up in experimental vehicles still in pre-production, including plug-in hybrids. Up until that point no other manufacturing industry had been bailed out in the current financial crisis. Of course it’s not the first time the automobile industries have been given government assistance. The Australian automotive industry has received on-going government subsidies since the 1980s. Most recently, PM Kevin Rudd granted a 6.2 billion dollar ‘green car’ package to Australian automotive manufacturers. His justification to the growing chorus of doubts about the economic legitimacy of such a move was: “Some might say it's not worth trying to have a car industry, that is not my view, it is not the view of the Australian government and it never will be the view of any government which I lead” (The Australian). Amongst the many reasons for the government support of these industries must include the extraordinary interweaving of discourses of nationhood and progress with the success of the car industry. As the last few months reveal, evidently the mantra still prevails of “what’s good for the country is good for GM and vice versa”, as the former CEO of General Motors, Charles “Engine” Wilson, argued back in 1952 (Hirsch). In post-industrial societies like Australia it’s not only the economic aspects of the automotive industries that are criticised. Cars seem to be slowly losing their grip on identity-formation that they managed to maintain throughout “the century of the car” (Gilroy). They are no longer unproblematically associated with progress, freedom, youthfulness and absolute autonomy. The decline and eventual death of the automobile as we know it will be long, arduous and drawn-out. But there are some signs of a post-automobile society emerging, perhaps where cars will still be used but they will not dominate our society, urban space and culture in quite the same way that they have over the last 50 years. Urry discusses six transformations that might ‘tip’ the hegemonic system of automobility into a post-car one. He mentions new fuel systems, new materials for car construction, the de-privatisation of cars, development of communications technologies and integration of networked public transport through smart card technology and systems (Urry, Mobilities 281-284). As Paterson and others have argued, computers and mobile phones have somehow become “more genuine symbols of mobility and in turn progress” than the car (157). As a result, much automobile advertising now intertwines communications technologies with brand to valorise mobility. Car sharing goes some way in not only de-privatising cars but also using smart card technology and networked systems enabling an association with mobility futures. In Automobile Politics Paterson asks, “Is the car fundamentally unsustainable? Can it be greened? Has the car been so naturalised on our mobile horizons that we can’t imagine a society without it?” (27). From a sustainability perspective, one of the biggest problems with cars is still the amount of space devoted to them; highways, garages, car parks. About one-quarter of the land in London and nearly one-half of that in Los Angeles is devoted to car-only environments (Urry, “Connections” 29). In Sydney, it is more like a quarter. We have to reduce the numbers of cars on our roads to make our societies livable (Newman and Kenworthy). Car sharing provokes a re-thinking of urban space. If one quarter of Sydney’s population car shared and we converted this space into green use or local market gardens, then we’d have a radically transformed city. Car sharing, not to be confused with ‘ride sharing’ or ‘car pooling,’ involves a number of people using cars that are parked centrally in dedicated car bays around the inner city. After becoming a member (much like a 6 or 12 monthly gym membership), the cars can be booked (and extended) by the hour via the web or phone. They can then be accessed via a smart card. In Sydney there are 3 car sharing organisations operating: Flexicar (http://www.flexicar.com.au/), CharterDrive (http://www.charterdrive.com.au/) and GoGet (http://www.goget.com.au/).[1] The largest of these, GoGet, has been operating for 6 years and has over 5000 members and 200 cars located predominantly in the inner city suburbs. Anecdotally, GoGet claims its membership is primarily drawn from professionals living in the inner-urban ring. Their motivation for joining is, firstly, the convenience that car sharing provides in a congested, public transport-challenged city like Sydney; secondly, the financial savings derived; and thirdly, members consider the environmental and social benefits axiomatic. [2] The promotion tactics of car sharing seems to reflect this by barely mentioning the environment but focusing on those aspects which link car sharing to futuristic and flexible subjectivities which I outline in the next section. Unlike traditional car rental, the vehicles in car sharing are scattered through local streets in a network allowing local residents and businesses access to the vehicles mostly on foot. One car share vehicle is used by 22-24 members and gets about seven cars off the street (Mehlman 22). With lots of different makes and models of vehicles in each of their fleets, Flexicar’s website claims, “around the corner, around the clock” “Flexicar offers you the freedom of driving your own car without the costs and hassles of owning one,” while GoGet asserts, “like owning a car only better.” Due to the initial lack of interest from government, all the car sharing organisations in Australia are privately owned. This is very different to the situation in Europe where governments grant considerable financial assistance and have often integrated car sharing into pre-existing public transport networks. Urry discusses the spread of car sharing across the Western world: Six hundred plus cities across Europe have developed car-sharing schemes involving 50,000 people (Cervero, 2001). Prototype examples are found such as Liselec in La Rochelle, and in northern California, Berlin and Japan (Motavalli, 2000: 233). In Deptford there is an on-site car pooling service organized by Avis attached to a new housing development, while in Jersey electric hire cars have been introduced by Toyota. (Urry, “Connections” 34) ‘Collaborative Consumption’ and Flexible, Philandering Subjectivities Car sharing shifts the dominant conception of a car from being a ‘commodity’, which people purchase and subsequently identify with, to a ‘service’ or network of vehicles that are collectively used. It does this through breaking down the one car = one person (or one family) ratio with one car instead servicing 20 or more people. One of Paterson’s biggest criticisms concerns car driving as “a form of social exclusion” (44). Car sharing goes some way in subverting the model of hyper-individualism that supports both hegemonic automobility and capitalist structures, whereby the private motorcar produces a “separation of individuals from one another driving in their own private universes with no account for anyone else” (Paterson 90). As a car sharer, the driver has to acknowledge that this is not their private domain, and the car no longer becomes an extension of their living room or bedroom, as is noted in much literature around car cultures (Morris, Sheller, Simpson). There are a community of people using the car, so the driver needs to be attentive to things like keeping the car clean and bringing it back on time so another person can use it. So while car sharing may change the affective relationship and self-identification with the vehicle itself, it doesn’t necessarily change the phenomenological dimensions of car driving, such as the nostalgic pleasure of driving on the open road, or perhaps more realistically in Sydney, the frustration of being caught in a traffic jam. However, the fact the driver doesn’t own the vehicle does alter their relationship to the space and the commodity in a literal as well as a figurative way. Like car ownership, evidently car sharing also produces its own set of limitations on freedom and convenience. That mobility and car ownership equals freedom—the ‘freedom to drive’—is one imaginary which car firms were able to successfully manipulate and perpetuate throughout the twentieth century. However, car sharing also attaches itself to the same discourses of freedom and pervasive individualism and then thwarts them. For instance, GoGet in Sydney have run numerous marketing campaigns that attempt to contest several ‘self-evident truths’ about automobility. One is flexibility. Flexibility (and associated convenience) was one thing that ownership of a car in the late twentieth century was firmly able to affiliate itself with. However, car ownership is now more often associated with being expensive, a hassle and a long-term commitment, through things like buying, licensing, service and maintenance, cleaning, fuelling, parking permits, etc. Cars have also long been linked with sexuality. When in the 1970s financial challenges to the car were coming as a result of the oil shocks, Chair of General Motors, James Roche stated that, “America’s romance with the car is not over. Instead it has blossomed into a marriage” (Rothschilds, Paradise Lost). In one marketing campaign GoGet asked, ‘Why buy a car when all you need is a one night stand?’, implying that owning a car is much like a monogamous relationship that engenders particular commitments and responsibilities, whereas car sharing can just be a ‘flirtation’ or a ‘one night stand’ and you don’t have to come back if you find it a hassle. Car sharing produces a philandering subjectivity that gives individuals the freedom to have lots of different types of cars, and therefore relationships with each of them: I can be a Mini Cooper driver one day and a Falcon driver the next. This disrupts the whole kind of identification with one type of car that ownership encourages. It also breaks down a stalwart of capitalism—brand loyalty to a particular make of car with models changing throughout a person’s lifetime. Car sharing engenders far more fluid types of subjectivities as opposed to those rigid identities associated with ownership of one car. Car sharing can also be regarded as part of an emerging phenomenon of what Rachel Botsman and Roo Rogers have called “collaborative consumption”—when a community gets together “through organized sharing, swapping, bartering, trading, gifting and renting to get the same pleasures of ownership with reduced personal cost and burden, and lower environmental impact” (www.collaborativeconsumption.com). As Urry has stated, these developments indicate a gradual transformation in current economic structures from ownership to access, as shown more generally by many services offered and accessed via the web (Urry Mobilities 283). Rogers and Botsman maintain that this has come about through the “convergence of online social networks increasing cost consciousness and environmental necessity." In the future we could predict an increasing shift to payment to ‘access’ for mobility services, rather than the outright private ownerships of vehicles (Urry, “Connections”). Networked-Subjectivities or a ‘Digital Panopticon’? Cars, no longer able on their own to signify progress in either technical or social terms, attain their symbolic value through their connection to other, now more prevalently ‘progressive’ technologies. (Paterson 155) The term ‘digital panopticon’ has often been used to describe a dystopian world of virtual surveillance through such things as web-enabled social networking sites where much information is public, or alternatively, for example, the traffic surveillance system in London whereby the public can be constantly scrutinised through the centrally monitored cameras that track people’s/vehicle’s movements on city streets. In his “sociologies of the future,” Urry maintains that one thing which might save us from descending into post-car civil chaos is a system governed by a “digital panopticon” mobility system. This would be governed by a nexus system “that orders, regulates, tracks and relatively soon would ‘drive’ each vehicle and monitor each driver/passenger” (Urry, “Connections” 33). The transformation of mobile technologies over the last decade has made car sharing, as a viable business model, possible. Through car sharing’s exploitation of an online booking system, and cars that can be tracked, monitored and traced, the seeds of a mobile “networked-subjectivity” are emerging. But it’s not just the technology people are embracing; a cultural shift is occurring in the way that people understand mobility, their own subjectivity, and more importantly, the role of cars. NETT Magazine did a feature on car sharing, and advertised it on their front cover as “GoGet’s web and mobile challenge to car owners” (May 2009). Car sharing seems to be able to tap into more contemporary understandings of what mobility and flexibility might mean in the twenty-first century. In their marketing and promotion tactics, car sharing organisations often discursively exploit science fiction terminology and generate a subjectivity much more dependent on networks and accessibility (158). In the suburbs people park their cars in garages. In car sharing, the vehicles are parked not in car bays or car parks, but in publically accessible ‘pods’, which promotes a futuristic, sci-fi experience. Even the phenomenological dimensions of swiping a smart card over the front of the windscreen to open the car engender a transformation in access to the car, instead of through a key. This is service-technology of the future while those stuck in car ownership are from the old economy and the “century of the car” (Gilroy). The connections between car sharing and the mobile phone and other communications technologies are part of the notion of a networked, accessible vehicle. However, the more problematic side to this is the car under surveillance. Nic Lowe, of his car sharing organisation GoGet says, “Because you’re tagged on and we know it’s you, you are able to drive the car… every event you do is logged, so we know what time you turned the key, what time you turned it off and we know how far you drove … if a car is lost we can sound the horn to disable it remotely to prevent theft. We can track how fast you were going and even how fast you accelerated … track the kilometres for billing purposes and even find out when people are using the car when they shouldn’t be” (Mehlman 27). The possibility with the GPS technology installed in the car is being able to monitor speeds at which people drive, thereby fining then every minute spent going over the speed limit. While this conjures up the notion of the car under surveillance, it is also a much less bleaker scenario than “a Hobbesian war of all against all”. Conclusion: “Hundreds of Cars, No Garage” The prospect of climate change is provoking innovation at a whole range of levels, as well as providing a re-thinking of how we use taken-for-granted technologies. Sometime this century the one tonne, privately owned, petrol-driven car will become an artefact, much like Sydney trams did last century. At this point in time, car sharing can be regarded as an emerging transitional technology to a post-car society that provides a challenge to hegemonic automobile culture. It is evidently not a radical departure from the car’s vast machinic complex and still remains a part of what Urry calls the “system of automobility”. From a pro-car perspective, its networked surveillance places constraints on the free agency of the car, while for those of the deep green variety it is, no doubt, a compromise. Nevertheless, it provides a starting point for re-thinking the foundations of the privately-owned car. While Urry makes an important point in relation to a society moving from ownership to access, he doesn’t take into account the cultural shifts occurring that are enabling car sharing to be attractive to prospective members: the notion of networked subjectivities, the discursive constructs used to establish car sharing as a thing of the future with pods and smart cards instead of garages and keys. If car sharing became mainstream it could have radical environmental impacts on things like urban space and pollution, as well as the dominant culture of “automobile dependence” (Newman and Kenworthy), as Australia attempts to move to a low carbon economy.
