Is it time to start calling out bad cyclists?

I accept there is a case for cyclists being seen to be following the rules but I would also argue that judicious infringement of the rules can demonstrate the validity of exempting cyclists from certain rules. By showing certain rules can be broken without impact on other road users you could strengthen the case for allowing things like left turns on red.

Curiously enough having just read this I went up to Stoke Newington Church St and noticed that Edward's Lane has been made two-way for cyclists now. In essence, formalising something that has been happening for years in the way you suggest.
