In reply to James Malloch:
I have been cycling in London for eighteen months. Cycling in London is actually alright, despite what you might hear. It is certainly better than elsewhere in England simply because the drivers are more accustomed to sharing with bicycles - at least some of them know what to do.
The cycle "super highways", however, have always felt worse than useless to me. In my experience, apart from a short stretch of segregated lane across Southwark bridge, they're just blue paint on otherwise entirely inadequate roads. (I spend most of my time within a quadrilateral with corners at Camden, the Isle of Dogs, Waterloo and Kensington)
Black cabs still cut you up to pick up passengers, across the blue paint. Parking spaces are still demarcated where the cycle lane should run and, like all cycle lanes, they begin and end abruptly, without warning and in completely obtuse locations. After a while, I've simply learned to ignore the blue paint.
