I was once on a London bus that got stopped by the police for jumping a red light.

It was at Hyde Park Corner, heading north toward Park Lane - the light guarding the intersection with Knightsbridge turned red, the bus sailed through, and I think a nearby police car just happened to notice. Pulled the bus over and had a word with the driver, nothing more I think, but it was curiously reassuring.

I agree with you (as a former cycle commuter too) that drivers in London jump the lights far more than most people realise. If you go out for a half-hour walk and pay attention, you're highly likely to see it at least once.
