"I feel that riding slowly between 2 lines of almost static trafic is acceptable. "

The law says otherwise...there are TWO lanes,and a cyclist is legally required to be in one or the other, unless there is a marked lane especially for them.....which I approve of when 'possible'.

Sadly, I see more cases of cyclists...motor & pedal....abusing the rules than I see of motorists harassing cyclists. I do NOT approve of motorists refusing to give cyclists their rights or putting them in danger, but sharing the road has to be done by both sides.
