I am always careful crossing traffic lights/ pedestrian crossings. Tonight I got off the train at East Dulwich station, said to my girlfriend that this is the best pedestrian crossing in London, as soon as you press the button the lights change. Voila, the lights changed, a bus stopped and we started crossing the road. Light on Green but some idiot in a car overtook the bus and just missed hitting me and my girlfriend by inches! Really not sure what you can do to stop this happening...... I suppose in future I will treat green lights as just a warning and not absolute. Beware!
