A blunt force object (such as a hammer or crowbar), carried on a motorcycle, used to extract revenge. When a vehicle is driven too carelessly next to a rider, and they are subsequently almost run over, the "traffic cop" is withdrawn from its respective sheath, and used to smash the windshield of the offending party.
