On Nov. 30, 1965, consumer advocate Ralph Nader published Unsafe at Any Speed, a landmark book that helped usher in the modern auto safety movement in America.
The book prompted Congress in 1966 to create the agency that became NHTSA in 1970. No longer would the auto industry be self-regulating when it came to safety.
Though the 277-page book is often linked in its entirety to the Chevrolet Corvair, only one of its eight chapters deals with the rear-engined GM compact, which was built from 1959 to 1969.
The first-generation Corvair had a rear suspension design that could cause accidents, sometimes fatal, in certain conditions if the tires were not properly inflated. GM redesigned the car in 1965 and fixed the problem.
