Is it time to start calling out bad cyclists?

They are enforceable, in the same way that normal stop lines are enforceable - but cameras are not set up to enforce them, and popo is often ignorant of how they are supposed to work.

Motorists in boxes ≠ Crime & fine.

They do seem to encourage cyclists to always try and get to the front of traffic though, which can't be a good thing.

Just about every single junction is littered with cyclists forcing their way to the front, causing bottle necks - irrespective of road condition - even when there is NO box. I'm struggling to see the point. Help me.
