scare-mobile

A cop car that was once a cop car, but after a police auction or something, it is now in the hands of just some random person. (It may or may not have all the accessories a normal cop car has). When driving down the road in a neighborhood, it may scare the crap out of some people who are on the road into slowing their vehicles down so they don't get busted. It may even disperse a potential drug deal in progress.
