Last December I experienced the traffic in India first hand. A big difference between the formal and informal rules!! One needs to honk the whole time to let people in front of you know you are there. People drive all kind of directions at the same time, and cows and other animals share the road with you too.
The video below shows the experience ambulance drivers have in India in contrast to a European or North American situation. In India nobody give way to the ambulance and the patient dies, in European and North American countries lives are saved due to different social norms.
Hopefully videos like this will raise awareness and change some of the norms people use in Indian traffic.
