I'm an avid urban cyclist. My preference is for you to behave the same way as if I'm driving a car. Pass me if you can. If you're alongside me, a gentle tap on my brake will get rid of you quickly enough. ;-)

I will admit to having a mildly "political" motive, in that I would like drivers to have a positive experience dealing with cyclists. So I'm probably more courteous than the bare minimum required by the traffic laws. I get out of the way if I'm backing up traffic, whether driving a car or riding my bike.

My general preference is to find routes where there's minimal car traffic.
