Most Americans refused to wear seat belts even if they prevented deaths in car crashes. Manufacturers also realized that they could sell cars for their safety features. They added lamination to windshields a thin plastic layer between glass layers that keeps it from shattering as readily. They, also added energy-absorbing steering columns. New safety bumpers were designed that did not crush with low-speed collisions. Ford pursued other options. Many Americans had cars with seat belts, but few passengers wore them. Ford looked at data from the UCLA Institute of Transportation and Traffic Engineering. They conducted experiments such as putting humanform dummies cars and crashing them. The dummies were wired to show what happens to people, in a crash. Ford designed an air bag which would inflate on impact. Using data from the dummy experiments, they found the bags would give adequate crash projection. People...
