I have had a Dump truck drive ride my rear tire for about 500m to the red light. He was on the horn the entire way, it's a 4 lane road (2 each way), plenty of room for him to go around. At the light, he was half-way out of the cab when I offered him the stare. It worked! I'm 5'8" and 160 lbs, not scary at all.
I have also had a lady tell me to get off the road since I was not a car! I told her that the Ontario Highway Traffic Act says I have to be here, and told her she needs to read it.
For a smaller city the others, Hamilton sure has some angry, cycling-unfriendly drivers!
