My impression was that this nice weather had really brought out the cyclists. So repeated my counts at Dockhead this morning (July 17th). Compared with last October there were 66% more cyclists, an amazing 880 per hour. All motorised traffic (cars, motorbikes, vans, buses, lorries) was down 10% at 570 per hour. So for every 2 motorised vehicles there were 3 cyclists. It does not look like that because cyclists take up so little road space. But when you start counting there really are a lot of bicycles out there.
For those who do not know it, Dockhead is the Jamaica Road-Tooley Street junction on the A200. On one of the main routes from SE London, close to Tower Bridge. Counts from 8:08 to 8:45.
