It seems to be filmed from a cable car, which probably doesn't do more than 5mph, but the cars and even horse carts are overtaking it. As are a couple of cyclists. Of course it's not directly applicable to anything in Britain other than a few roads in London and maybe one or two other big cities eg Park Lane or Knightsbridge – and even then not since the end of the first world war, but it's interesting to see the chaos and how people navigate it. The only rule of the road, as we would think of it, that anyone seems to obey is driving more or less on the right. Overtaking is done wherever you can, on either side. Most pedestrians stroll across, one or two run. Look at the man 2:25, strolls across, turns back to avoid the cable car, almost gets run over by one in the other direction he's just passed, then resumes his journey! Nobody gets across in one take.
