A couple weeks ago, Mrs Minou and I are driving on the 13 south in the Dorval/Lachine area of Montreal on a quiet Saturday morning when we encounter an SQ CV doing radar on our side of the road. Didn't think much of it. Seconds later a sport bike passes us weaving between lanes at a "moderate" 150 clics or so.
I said, how come the radar didn't clock him when the trooper comes from behind lights on at the same speed. He had no chance unless the biker stopped or was caught further down the road by an other patrol car. And there was many escape routes in the area.
