Your rant looks very much like one of mine from a while back. And there are scores of other cyclists who have had the same experience.

My personal experience has more to do with driving than bicycling, though. Out here on Long Island, we have a lot of cyclists who insist on riding against traffic. Many of them are non English-speaking day workers, so I can't even gently explain to them why this is so dangerous. One of these days, though, I'm going to come to an intersection in my car, look right, and go, and there's going to be a cyclist coming up on my right. You know what happens next...
