"Bumpersticker, no parking, insurance" joke

Seen on the back of a truck (on the bumper):
< PASSING SIDE ===== SUICIDE ->
Sign on garage: "Don't even THINK of parking here!"
And reportedly on another: "Vehicles found parked here will be stolen by professional thieves, and left stripped somewhere in New Jersey."
