Although I think the cyclists are idiots an should find better places to ride, I am fairly polite to them and do my part to share the road.

It is a lot easier to share a lane with them on my motorcycle. I even try to stay off the throttle so the noise doesn't spook them when I go by. And I have never been tempted to "bang bars" with them either. (You motocross/super cross guys know the drill.)
