Personally, I did not see anything the dangerous in the film for the existing conditions. The traffic is so slow and the impediments immobile for the most part that going around them did not seem to pose a hazard to any of the cyclists.

With side segregated side paths, you have to stop and wait for a light to take a left turn (like a pedestrian). If there was a sufficient network of side paths (every other street?) it might be an improvement.
