This video, by regular commuter Gaz, is of Cycling Superhighway 7 going from Elephant & Castle past Kennington Park towards Clapham. The blue paint guides cyclists to move out of the bus lane into the left hand side of a lane used by motor traffic turning left towards Brixton or Cambewell. Cyclists aren't turning left here with the motor traffic but are following the cycle superhighway straight on to Clapham.
Recipe for conflict? It's an appalling piece of design as the video shows.
