Beware of startled pedestrians in the road jumping backwards into the gap that you are aiming to ride. I think this behaviour is the cause of many ped-cyclist collisions in the road. I am not aware of any cyclist who aims at where the pedestrian are or where the pedestrian can be projected to be at time of intercept.
I think some aim to pass far enough in front that they should be clear, but then the zombie wakes up to the fact they're in a live traffic lane and starts running: crunch!
Most of the time, if the cyclist passes outside the area a walker might trip or fall into (2m backwards, a bit more forwards), it'll be safe, but far too many city riders seem to close pass walkers at high speed when they should have slowed to jogging pace at most. I don't understand why most other countries can cope with this and Brits can't. Is it because our cycling is still racing-dominated, all about average speeds and segments and koms and weight and power meters?
