I too use both my bike and my car to get around. Granted I cycle most of the time, but I drive enough to see the issue from both sides. What really perplexes me is why so many motorists become infuriated at the mere presence of a cyclist on the road with them. I realize the law gives equal rights to both drivers and cyclists, but I also have a keen awareness of the physics involved. In other words, I stay to the right except when it is absolutley necessary to take the lane and I will most allways yield even if I have the right of way if safety is a concern. I am as considerate as I can possibly be. That said, I have NEVER even seen a cyclist deliberately harass a driver, but drivers give me trouble nearly every day. I am not in any way advocating violence, but let's say I have no sympathy for the occasional motorist who gets pepper sprayed or punched in the face.
