I have to say Mr Hippo that you went further than I would. I may have given a bit of a warning shout if I felt it would help, but wouldn't bother having a word with the driver. You Helmet camera cyclists - always looking for trouble!
BTW it looks an interesting place to cycle - a bit chaotic but it seems that car drivers are more attuned to other people using the roads (pedestrians, cyclists, mopeds, street sellers) than many in the UK would be. Traffic speeds are pretty high though. I have cycled in Brazil before now, and once you are used to the traffic flow it wasn't actually too bad, drivers weren't surprised to see other traffic in their way (although the accident rates on roads there is truly horrifying).
