Despite the ubiquity of automobility, the reality of automotive death is hidden from everyday view. There are accident blackspots all over the roads that we use and go past every day but the people that have died there or been injured are not marked, unless by homemade shrines and personal memorialization. Nowhere on the planet is this practice as densely actioned as in the United States. Road Scars is a highly visual scholarly monograph about how roadside car crash shrines place the collective trauma of living in a car culture in the everyday landscapes of automobility. Roadside shrines—or road trauma shrines—are vernacular memorial assemblages built by private individuals at sites where family and friends have died in automobile accidents, either while driving cars or motorcycles or being hit by cars as pedestrians, bicyclists, or motorcyclists. Prevalent for decades in Latin America and in the American Southwest, roadside car crash shrines are now present throughout the U.S. and around the world. Some are simply small white crosses, almost silent markers of places of traumatic death. Others are elaborate collections of objects, texts, and materials from all over the map culturally and physically, all significantly brought together not in the home or in a cemetery but on the roadside, in drivable public space—a space where private individuals perform private identities alongside each other in public, and where these private mobilities sometimes collide with one another in traumatic ways that are negotiated in roadside shrines. This book touches on something many of us have seen, but few have explored intellectually.
