It is Tavistock St. I kind of appreciate it, but then I have spent too long playing Mario & Sonic's Dream Olympic sports. Frankly it could only be improved if I had to bounce off a giant mushroom to get across Tavistock Square.
Back in the realverse, it is a bit odd. I think they planned 90% of the cycle route, then stalled when attempting to figure out how to join up the sections so took the best option available in these situations and went to the pub. Any bad idea starts too looks progressively like a good idea when viewed through a succession of beer glass bottoms. Quick scratch of the pencil on return to the office, and et voilĂ , one cycle route.
As said elsewhere, I am not sure what this cycle lane is supposed to do. It follows the path of perfectly reasonable and non-threatening road. And as a boon, if you use the lane, you end up waiting at the lights because traffic on the main road gets priority.
