Do you find anything odd about the cars on this road? No? Look again and you will notice that both the vehicles are on the wrong side of the road, which, in India is the right.
This is probably the only stretch of public road in Chennai where you are allowed - actually expected - to drive on the wrong side of a two-way street. Traffic on Luz Church Road - where the white car is turning in from - is only westbound, while Musiri Subramaniam Road, nearer to us, permits vehicles to only go east. This bit of road is where they changeover, if they need to. The flow is much smoother if you to stick to your right when making the U-turn.
Everyone has naturally adjusted to it, to the extent that quite a few of my friends - including some who use this route regularly - refused to believe me when I mentioned they were violating traffic rules!
