Is it time to start calling out bad cyclists?

Do you think? I used to commute by bike from Kichijoji to Shibuya every day and thought that by and large traffic responded much better to cyclists than in London. Everybody, even taxi drivers, seemed more aware and dare I say concerned about the presence of cyclists... the riding on the pavement thing is entirely different I grant you.

And that's the problem - most people ride on the sidewalk and those who do ride on the road generally ('proper cyclists' aside) have no idea what to do.

The motorists are, by and large, pretty good. The bike users are not.
