"I am surprised at how aggressive many pedestrians' comments are towards cyclists. I must say, as a pedestrian in London I hardly see any cyclists riding on the pavement. Of course I find it annoying when the occasional cyclist does not stop at the zebra crossing I'm about to walk over but I perceive London's motor traffic as a significantly higher stress factor. For example, having to twist my head in all directions at every junction to avoid being knocked over by turning cars which never give way to pedestrians. Maybe some of the stress of being a pedestrian in a very crowed city with narrow streets and aggressive (motor) traffic is channelled as aggression towards cyclists who are a more vulnerable and, for many people, pretentious minority."
