Very interesting thread. I realized while reading it that I pretty mcuh assume that I am anonymous on my commute. That is I think it doesn't really matter what I do because its not as if people see me specifically and form a view of me specifically. Howevr I am beginning to think that that is not true for a couple of reasons. One is that I had a verbal altercation with a nutso driver and then saw him a couple days later. Second is that logically I will see the same people if I ride at the same time which I usually do. Third I realize that I have a wife and kids and that it is more important that I get home safe then I be a one man defender of all cyclist rights. So I think I am going to try to be more courteous and less of a hardass. On the other hand You gotta give the newbs some slack. They may just need some time, some conditioning and some close calls to change their behavior. I just hope its close calls and not getting run over.
