This chapter concerns automobility, or the geographies created by the world’s 1 billion cars. Drivers are enmeshed in complex systems of automobility that greatly transcend driver and car, but form assemblages of people, things, ideas and power. The chapter traces the history of automobility, how it has varied over time, and then proceeds systematically to uncover the various systems that enter into its making, such as government policies, household behavior and planners and developers. It also explores the infrastructures, including global flows of petroleum, which are essential to the mobility enjoyed by so many. Finally, it offers a summary of the externalities imposed by driving, including fatalities, air pollution, health impacts and social inequality. The chapter concludes by speculating on the nature of an auto-free future.
