It's rare, but sometimes happens. I remember being nailed up at 55-56 and passing one on the right, on rt 2 going like 53 for some odd reason in the passing lane... I bet he was f***ing with his computer or something or trying to troll someone into passing him at a higher speed, more than likely. Some of the prick MSP types try to piss people off and induce a stop from it, its pretty retarded. The worst one I saw was an MSP bike cop weaving between the two outer lanes of 495 going about 63-67 mph, not signaling, nothing... just litterally put putting between the two lanes. I tried to pass him on the right f***er chirped his siren at me, so I backed away. Like seriously dude, you're creating a f***ing safety hazard with a chain of 900 cars going up 495 in a large turd block because you won't get out of the way.
