Double jeopardy, anybody?
"Over past few years, some states have adopted what's loosely (and euphemistically) called Driver Responsibility laws, sometimes sold to the public as "bad driver" taxes since they kick in after drivers lose a certain number of points on their licenses. Using these laws, states can come back to you later and legally bill you for amounts that far exceed, usually by multiples, whatever you agreed to pay in court. It doesn't matter if you live in another state. And if you don't pay, that state can make it a crime for you to drive within its borders again. If you do, the case will no longer be civil--it will be criminal."
I'll take "How To Repeatedly Screw The Driver" for $3,000, Alex!
