I avoid busy roads if at all possible and do most of my actual road riding in the early morning on the weekends. We have a lot of bike friendly trails around here so it's pretty easy to do. When I am on the road I don't care that I have the right of way, if there's cars and there is room then I'll move over to give them as much room as possible to pass. I want to live and I generally assume all people on the road in cars are bad drivers and could very easily hit me just because they can't tell how big their own vehicle is.
