I don't get this, but I hear it a lot. If I were in your position, I'd go after that, talking to his superiors until he had to go to night classes to learn the local traffic laws. I mean, I can understand random yahoos in cars thinking that bikes in the road are asking for trouble, it doesn't even surprise me terribly when the mayor of Toronto says it, but I'd like to think that cops who are supposedly there to "protect and serve" would at least know and understand, maybe even support, the basics rules of the road.
