I hope this isn't considered necro-posting around here. I had something similar happen to me a few weeks ago with the same section 182(2) infraction.
I was in the Napanee area on the 401. Came upon an OPP cruiser in the left lane who couldn't seem to maintain a steady speed, travelling anywhere from 90 up to 110, but who refused to change lanes or allow anyone to pass him. Myself and a growing que of cars were stuck behind this guy because anytime anyone wanted to pass when he was slowing down to 100 or less, he'd turn on his emergency lights and prevent the pass. I saw him do this at least 5 times over a span of 15min. We were going slow enough that transports had started catching us and the road ahead was pretty much clear of traffic since we were travelling slower than the normal flow of traffic.
I passed the cop when he again slowed from 110 and I decided not to follow suit. I passed him in the right lane going 110 and when I got ahead of him, he pretty much instantly pulled in behind me and lit me up.
I'm already planning to fight this in court. He gave me a long winded speech about pulling me over for my safety, accusing me of being the type of driver that gets involved in accidents, and then concluding his diatribe by giving me some advice about passing cops and how "other officers" don't like being passed. WTF?
What I'd like to know is if his use of the emergency lights and his driving behaviour gives me grounds to file a complaint with the OPP? I think what this guy did was disgusting and an abuse of his position.
