Refocus on safety and quality
With the publication of Unsafe at Any Speed: The Designed-In Dangers of the American Automobile by Ralph Nader, car manufacturers were exposed as resistant to introducing safety features such as seat belts.
According to History.com, by the mid-1960s, “American-made cars were being delivered to retail buyers with an average of twenty-four defects a unit, many of them safety-related.” By 1966, new federal standards for automotive safety were passed.
