As someone who was struck and injured by an uninsured driver, not only should uninsured drivers have their licenses suspended, any vehicle they are found operating or in possession of regardless of who owns it should be shredded and recycled with the scrap value going to a fund to compensate victims.
edit: also, I have been driving for 30 years and never been issued a ticket, been at fault in a crash, or had a single insurance claim except for chipped windshields. My insurance is so low I don't even know how much it costs. It is my assertion that operating vehicle in a manner that avoids accidents, fines, and court cases is easy, especially since I'm entirely average in my abilities, and I have very little sympathy for those who cannot do so.
