It's actually similar to a scheme a friend and I worked out a few years ago. Everyone gets, say, 3 paintballs a month. If you see someone doing something that you think is wrong (speeding, street racing, doing donuts on your lawn, parking across a line, etc), you can paintball them. Heck, use all 3 if you want.
If the cops see a car with more than a certain number of paintball hits, they get pulled over and given a ticket for being an shiny happy person.
The trick is the limited number of paintballs. You have to consider who you're going to peg.
Come to think of it, it sounds like something the Lemons organizers might do - mob rule, crush the guy nobody likes for whatever reason.
The safest car I own is the old Cadillac. Because it loves to just cruise at 5 under. I swear I'm gonna have to get myself a nice hat if I keep driving like this.
