"Amazing Things Your Automobile Can't Do" makes the obvious point that manufacturers arn't bringing all their features to the US for fear of litigation (just like some US doctors are refusing to treat lawyers).
The other hint I got from it was "Litigious US = percieved unsafe, high crime rate. Non-litigious Japan = perceived safe, low crime rate". Whilst there's more to it than that, there's something in it. Litigation abuses the law, which once done reduces one's respect for it. More justification for my "Ministry of Common Sense", the all-powerful body that can throw out any court case if the plaintiff lacks common sense (eg. "I put my dog in the microwave and it died. The microwave didn't say I couldn't, so I'm sueing").
