How much do you think it cost automakers to add seat-belts to their cars? Probably not that much, when compared with the overall cost of the car. This made it seem incredible to some of the public, for a time, that car manufacturers wouldn't be fighting legislation to force them to add seat-belts in good faith.
But, there was, and always is, a lager issue at hand. To the auto industry seat belts represented public responsibility for the overall safety of their product.
@Lyle @futurebird I have started to wonder if the imbalance between the perceived safety of car users, and the actual safety of other road users isn't the causes of more harm than the safety system prevents.
For every car user we save; how many other road/street user do we kill or maim?
