Do you people really have this much trouble with drivers? Sure, I occasionally get drivers doing annoying things, but I also get the same behavior from pedestrians and other cyclists, and I know that there have been occasions where I've done things in traffic that make me think or say "oops, sorry!" Everyone screws up one in a while, but I must share the road with 1000 cars each day, 50 other cyclists, and hundreds of pedestrians, in a big city that's known for drivers who tend to ignore the rules, and I rarely have any problems. Certainly not enough to start stereotyping people into "annoying motorist" categories.
