There may be other places this cop pulls this off–a moving speed trap: he works for Highway patrol: He gets up dangerously close to vehicles that are known to be slow like box trucks, as if he needs to pass, while shooting his radar out the back of the hwp white utility vehicle he drives. He gives the apparency that there is a slow moving vehicle to be passed but he never passes and his car is not marked on the back: instead he waits for someone to hurry up to get in line to pass and nails them. He will try to get you to pull over where the is no safe place to pull over and get up in your grill for waiting for a safe spot. Do not fall for it. I saw the same cop, just around the first gradual bend just after you get on the 522 going west, shooting a rear radar out the back of his rig. I am not sure what the speed limit is there but be careful as it’s dangerous where he sits to the right of fog line: a place only a desperate cop would sit and wait– there’s no room to miss him if you take that bend too tight…be care…
