My favorite encounter so far was when my wife and I were out riding one day. I was behind her, and some woman in a car passes me and lays on the horn right behind my wife. I took off past my wife and chased this lady (downhill, easy to do) I was right behind her the whole way. She freaks out and turns into a dead end street, then jumps out of her car screaming at me that we should have been on the sidewalk. She knows this because she rides a bike too, and that's where she rides.

I explained to her that coming up on a cyclist and blowing her horn was a good way to startle the cyclist and possibly throw them off balance, into the path of her car. She didn't seem to care.

I cannot take the stupidity of some people.
