GM certainly showed us the meaning of "corporate responsibility" when they produced the Corvair for several years. Of course, Ford did the same with their Pinto which tended to blow up in flames when hit from the rear. Well, after all, it was the consumer's fault for not asking if it would do that. Now, I know better, and always ask the dealer if the car I am buying tends to explode when hit. I am sure that he would tell me the truth, even if the government did not force him to.
You do realize that the government fought Ralph Nader equally as much as the big 3.
The government didn't change car safety...until they were forced to.
