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a vehicle is driven too carelessly next to a rider, and they are subsequently almost run over, the "traffic cop" is withdrawn from its respective sheath, and used to smash the windshield of the offending party.
"I fitted the frame of my bike with a traffic cop. Ya know....Just in case."
