Uh...it's not just about hurting someone else. If you t-bone a $100k car with your 20 year old chevy the owner of the $100k car is really going to hope you have insurance. Even more important, the insurance company of the $100k car is going to want the chevy driver to have insurance. Following the money will show that the law requiring insurance was bought by insurance companies in the first place.
If I crash into someone's $100K car with a hammer, I suppose I need hammer swinging insurance. I think maybe I could be sued in civil court for the damages and be ordered to pay restitution in some other way, even if I didn't have insurance. Why exactly would it matter to the expensive car's owner if I had my insurance company pay the bills or if I whipped out a checkbook and paid? Why do I need auto insurance if I have say $5 million sitting in an "accident fund" for just these sorts of things?

Why does this not surprise me at all?
