This may not actually be at all related, but I remember reading somewhere that in some places they have a specific bumper sticker (that says something innocuous like DRIVE SAFELY) that is reserved for people who don't often drive their cars after dark.
That way if a cop's on patrol at 2am and he sees a car with this bumper sticker driving around, he knows there's a good chance the car's been stolen.
