>I know that I'm "preaching to the choir"<

Yes, you are. You acted appropriately in the situation in which you found yourself and I'm glad you could unburden your feelings.

Most people know the rules of behavior. It's all the more shocking, then, when a serious rider seriously breaches etiquette. For the most part, it's casual, rather than serious bike riders, who break the rules.

No, arrogant behavior isn't limited to people who wear bike shorts made of lycra, anymore than it is to those who wear cargo shorts made of cotton. Come to Venice Beach, CA, on a Sunday afternoon, and note how individuals and groups (friends and families) of casual riders meander dangerously all over the bike path. And there are plenty of pedestrians who walk on the bike path, too.

That's why many "serious" bicyclists only ride that path early and late in the day - but that takes all the fun out of people-watching.
