Currently only 10-15 per cent of India — even in its richest cities — commutes by car. But private cars take up over 90 per cent of the existing road space. And remember, this is when only a small minority drives. How will we make space for the rest to drive — space on the road for the car to move and space in the air for us to breath? This is the reason for this book. Without a mobility transformation, Indian cities can never win the war on foul air and toxins emitted by vehicles.
