What rubbish, I have nothing to do with how other people ride and they me. Do you blame / associate every driver with every bad / good one?
Err... At one level, yes. When I drive, I am associating myself with an activity and the other people who participate in that activity, whether I like it or not. Ditto cycling.
When yet another concrete bypass is driven through green fields, I am part of the community that brought that about.
When yet another London driver curses a cyclist shooting a gap, or another pedestrian forms the impression that they were nearly knocked over by a pavement cyclist, or another resident of Box Hill perceives it as unsafe because of the speed that groups of cyclists travel down it, I am part of the community that brought that about.
Community. It's part of being human. Ask not for whom the bell tolls...
