I've been walking across Tower Bridge with my bike very day this week, pretty much every other cyclist i've seen has done the same i.e. get off and push. So far the only people being dicks about it have been one guy on Tuesday evening on his bike, sitting on the saddle but propelling himself with one foot on the pavement going the same speed as everyone else walking - when asked why he didn't just get off and walk like everyone else his reply was "i don't want to wear out my cleats". This morning there was another guy scooting his bike through the crowds much faster than people walking. Apart from those two twats everyone else with a bike has been behaving as normal considerate people, contrary to that ES article.
