The streets of Mumbai are seldom quiet - day or night they echo to the sound of revving cars, rumbling lorries and the angry-wasp buzz of auto rickshaws. And then there are the horns.
In a city of 18 million inhabitants there are 1.8 million motor vehicles and the number is growing every day as more drivers take to the roads.
