In the middle of Wimbledon today.
At this (Digonal-Crossing) junction.
While all traffic lights were RED and all pedestrian lights were green.
A scooterist (non-rental), in black, no helmet or any other protective clothing, coming from the open road ahead at (I estimate) 20+ MPH blasted through, while all 4-way cars were stopped, and crossings, including the diagonal, were occupied by pedestrians.
He came down on the inside of the stopped cars and, mid junction, switched to the outside.
How he failed to hit someone is a miracle.
