You are right that the bicycle community does itself no favors with some of our behavior. We are working on it. I think the bigger issue I raised was about the Busses.
I am not sure there is anything that can be worked on ...
As a driver who lives in a very popular biking environment (and who has given some careful thought to the issues and has taken his own turns being a biker) I am increasingly convinced that riding a bike and driving a car on the same roads are fundamentally antagonistic behaviors.
I find that unfortunate, but I think it might be the case.
