There's an interesting quote at the end of this article -- something that's crossed my mind when I see a cyclist behave badly in traffic...
How many motorists who just had to deal with that person's actions are now agitated with ALL cyclists?
Quote from article:
"Oh, we hate these guys," says Rogers. "We absolutely hate them. The driver you tick off is the one who's going to run me off the road."
