'Cause it's the cyclists that need educating...

Anyone who cycles in London sees lorry drivers on mobiles, reading paperwork, jumping red lights and overtaking dangerously. Skip and flat bed scaffolding lorries are the worst in my experience, often driven by homicidal thugs. It's all well and good targetting cyclists, but it's the lorry drivers who need policing.

A poster campaign to warn cyclists not to perform dangerous manouvres isn't the same as policing them - you seem to be suggesting that you believe these posters are criminalising cyclists in some way?
