School busses are a tough one. They are not allowed to cross the center line, under any circumstances. So if you encounter one on a lane where there isn't room to pass, they take unnecessary risks. Their first responsibility (as it should be) is to the children they are transporting. I do think the laws are going to need updating as more and more people bike to work.

DH would run into the same school bus every day on his old commute. Once he figured out why this was such a bad interaction, he got in the habit of pulling into a driveway to let the bus pass. Once the bus figured out that DH would do this for him, the bus driver learned to wait for DH to do this, instead of zooming right past him. Of course, that was an unusual situation.

Oh, and road rage on bikes? Yeah, it happens. I've seen both my DH and a few other riders I know (all male, come to think of it), chase down cars that drove like jerks. Personally, I agree with being the ambasador and I make an extra added effort to visually thank those drivers that do the right thing. Positive reinforcement!!
