>>The reason the Big 3 auto makers resisted offering safety devices is they believed that it would imply their product was unsafe.
I think that is part of the problem, but the other part of the problem is lawyers. If a manufacturer of *any* product, makes improvements to it to improve safety, then lawyers jump on that as an admission that the previous version was unsafe, and thus they file a lawsuit (after finding a victim of course) and go to court and say basically: look, my client got hurt, the company has admitted that the old version of product xxx is unsafe because they added these safety enhancements...blah blah blah.
It has been a succesfully strategy. So unfortunately, companies are forced to decide if it will cost more to make the enhancements or not make the enhancements based on the lawsuits that will happen either way. Kind of an unfortunate situation for every but the lawyers...
