Damn, we have the same drivers. Never signal and lanes are treated as suggestions.
I've travelled to a few countries in my time, but Indian traffic takes the cake.
You can pull up to an intersection in New Delhi, with 4 lanes marked each way. A row of about 7 cars will form. Two of them will be turning right (not the right two lanes), two will be going left (again, not the left two), two will be going straight ahead, and one will be headed in the wrong direction entirely.
The next row of traffic will vary from the first.
What amazes me is that there's relatively few accidents. They use the horn all the time, as an indication to others that they're there. "I'm here, I'm here, I'm still here, did you know I'm here, I'm here" over and over again.
Then you get the cows on the roads. And the people wandering around.
It's chaos.
I miss travelling to India. After the third trip, I even stopped fearing for my life when being driven around.
