I pitched an idea for punishment for this behavior a while back (I'm in Portland, where street racing is a major issue right now), and got downvoted like crazy for it, but I'll try again here. Each time they are caught, surgically remove one finger. Either they'll take the hint that people want them to stop, or if they keep it up they won't be able to grip the steering wheel. Win-win.
