Any Londoners tried the cycle superhighways yet? Are they all segregated yet? Googled a bit. hard to be sure. I've seen some pictures of motorists driving on them which is just outrageous, same as normal cycle lanes, but I found a comment on wikipedia that seemed to suggest that some may have been segregated at a later date. Thinking of cycling into central London on one, by the looks of it I could get most of the way to the other side of London on them.
