Thought I'd ping you to the post above. Take a look at the articles. Compulsory auto insurance raised both the societal and individual costs of auto accidents. I agree it's a responsible thing to do, and I have always had insurance. Making it compulsory however, was a bad idea. Did nothing but raise the rates for those responsible enough to carry it in the first place.
Yes, I did a quick look at the links you posted and at first glance, I do not believe them. (lies) However, I will read them more in depth and it may change my mind. Common sense tells me that if everyone has liability, you will at least get something from the A-hole that hits you, better than nothing. Also, at first glance, more payers should should not drive the cost higher unless the non-payers that are forced to pay are more accident prone and therefore cause the payout from insurance co. to go higher, that would drive up the cost for everyone. BUT, that does help the little guy that gets his/her old truck trashed.
