A big chunk of the US insurance is the Liability portion. That's because in the US, everyone like to SUE the crap out of everyone else. You tap someone on the bumper, next thing you know you get sued for $1 million with the guy claiming (among other things) that he can't "please" his wife anymore in bed because you screwed up his spine (never mind that it was a 2 mph bumper bump). The lawyers here get very creative!

There's no perfect country, every place has its' upside and its' downside.
