Terrible things happened in the 1950s and 1960s. McCarthyism got loose for a short period. President John F. Kennedy and his brother Bobby were murdered, as was Martin Luther King, perhaps by their own government. The reliance on fear to keep the profitable cold war going and the elimination of those who would change course are antecedents of the present. We still suffer from them.
The difference is that then enough Americans had a frame of mind that had space for the optimism that permitted blacks to be legislated into full citizenship and for the protests that brought to an end the military/security complex's profitable aggression in Vietnam.
Perhaps elegant cars had a civilizing influence and contributed to that frame of mind. Get Washington out of car design. It might help to restore our humanity from the brutality that surrounds us.
