Unsafe at Any Speed: The Designed-In Dangers of the American Automobile is a book by Ralph Nader, published in 1965, detailing his claims of resistance by car companies to the introduction of safety features, like seat belts, and their general reluctance to spend money on improving safety. One of the examples of the book was General Motors' Chevrolet Corvair, which had a suspension that made it liable to roll over. GM responded in two ways, by trying to silence Nader and also by improving the Corvair's suspension. GM President James Roche was forced (on March 22, 1966) to appear before a Senate subcommittee, and to apologize to Nader for the company's campaign of harassment and intimidation.
