In a pure free market system, Ford would have been allowed to continue making Pintos, knowing they exploded when hit in the rear. Ultimately, the market would have protected drivers, I guess -- most ppl don't like getting blown up and dying on fire in their cars, and will stop buying Pintos. There are such things called "public goods" that the free market is not designed to provide. Worth looking into.
