I spent 6 days in Portland last week. Seemed like there was always somebody on a bicycle within your field of vision, especially in the local business district areas like Hawthorne. At one intersection, there were eight cyclists waiting together to cross the street. It felt unreal to be riding along with so many other commuters.
It didn't feel like their was tension in the air between road users. Bicycles, pedestrians, and motorists seem to coexist fine by all accounts. Even at stop signs, cyclists and motorists were taking their turns or motorists were "too nice" and would motion for cyclists to go through out of turn.
Coming from the Tampa Bay area, I couldn't ask for more than what Portland has as far as modal share and a feeling of belonging on the road. Bicycles are so ubiquitous there. It seems that hatred towards cyclists much be approaching that natural statistical occurrence of hatred that exists for us all, regardless of what we choose to use for transportation at any given time.
