So no association would be made in the mind of a cyclist that Red means stop. I find it terrifying that people would take to the roads on any form of transport and not no the required laws.
Well as a pedestrian when I walk diagonally across a cross roads (something I do all the time in London) I don't think the red traffic lights mean I should stop (as a pedestrian). What I learn from that is that cars (probably) won't drive through that part of the road and I use it to inform which way I look. The red light is there to control the cars, not the pedestrians. Novice cyclists may easily think the same, no?
