Lots of good ideas in this thread, and cyclists runnign busy stop signs piss me off, but even worse are the cyclists who ride on the wrong side of the street. I always seem to encounter them just when the traffic is busiest and I have to merge back into traffic (we have lots of streets that are larger than 1 lane, but smaller than 2 in both directions, excellent for cycling). They just give me a stupid look when I yell at them. I have stopped yelling at drivers because the last time I did, I also gave this lady the bird. She pulled over, got out and apologized for passing so close (I touched her mini-van). I am happy that she was so reasonable, but my temper and the cussing is just embarassing when you then have to speak to someone in a civil manner.

Incidentally another group who piss me off are the guys who drive their bikes to the trail...

Road rage happens to us all, I think I will borrow the Jesus idea =)
