I'm a subscriber from outside North America, but I like hearing about law. When airbags were new to the US, they were required by law. The makers, who always oppose every safety standard, also opposed airbags, and didn't spend effort making them safe, just barely legal. So when the makers got sued for the unsafe airbags, the makers argued that "compliance with legal minimums is proof of non-negligence". That argument failed, and the lawsuits were allowed to proceed. The makers then spent effort getting the very unsafe 1st generation airbags replaced with safer airbags. I don't remember how high that lawsuit got, I followed it in real-time back in the 80s and 90s, so forgive my memory. But it was a win for consumers.
