While bicycling, I've had many close calls with other cyclists running stops and reds. I fear them more than cars. After riding a "compact double" on a borrowed bike for the first time, I finally figured out why so many cyclists run stops and reds - because the shift pattern on a compact double from a start is a royal PIA. It also explains why they are total dogs off the line. Stopping is no big deal if you have proper gearing and an easy shift pattern. Does it ever occur to anyone that the reason courts seem to favor motorists to cyclists is that flagrant violations by cyclists have created a bias? The van was probably blowing his horn because he saw you run the previous light. I can only hope that I'm not the next cyclist he sees and he takes it out on me. If you want respect, show respect even if it inconveniences you for a moment.
