Crashes and wrecks are a part of NASCAR life. With three dozen vehicles traveling inches apart, the slightest nudge or tiniest malfunction can start a chain reaction that can lead to a high-speed crash. This book looks at what causes accidents, the forces in play during crashes, and the work car designers and safety engineers do to make sure even the worst wrecks are survivable. The book also looks at the head-to-toe safety gear worn by drivers, pit crews, and track personnel.
