In honor of the year's busiest travel week, NPR is doing a series on traffic safety, which inspired us to think about several recent Duke Press books nominally about the subject. Enda Duffy's The Speed Handbook: Velocity, Pleasure, Modernism returns to the early days of the automobile to examine how the experience of speed has always been political and how it has affected nearly all aspects of modern culture. Speed became the quintessential way for individuals to experience modernity, to feel modernity in their bones, particularly when that speed resulted in actual broken bones! Jeremy Packer looks at automobile safety in American culture in his book Mobility without Mayhem: Safety, Cars, and Citizenship. Packer analyzes how driving has been understood by experts, imagined by citizens, regulated by traffic laws, governed through education and propaganda, and represented in films, television, magazines, and newspapers. Packer, a motorcyclist himself, has an especially interesting chapter on how the motorcycle went from being seen as a cheap, easy mode of transport to a risky machine driven by outlaws. And finally, we have a new book out about the development of the anti-lock braking system (ABS). Ann Johnson's Hitting the Brakes: Engineering Design and the Production of Knowledge uses the development of ABS as a case study for examining the process of engineering design in which knowledge communities come together to produce new products and knowledge. Think about the rather tortured path from design to implementation as you stomp your own anti-lock brakes in traffic this week.
