I think it was Sweden which levies traffic fines based as a percentage of your annual income. Seems to work as a good deterrent for those who have no issues paying the fine.I caught up with a speeder who got pulled over twice, coming back from PA on the turnpike. Flew by me once, caught up with him after he was pulled over. Then he goes flying by again later. And I caught up with the same car again, pulled over. "Here is your sign."
