Is it time to start calling out bad cyclists?

There are few things more satisfying cycling in London traffic than preventing people riding down the gap between a vehicle and the kerb. The more ridiculous angle you have to put your bike at to stop them, the better.

The best ones are where you get an audible 'tut' from behind, or even a request to let them past. Which is stubbornly refused, obviously.

I used to do that but was amazed at the determination of other cyclists to squeeze into the smallest of gaps between me and the kerb, so I just wait in line and watch them.

Besides given my diminutive size, it wouldn't take much for one of them to 'gently' knock me over whilst passing.
