Every city has its unique mode of commuting. Kolkata is no exception. Thus one can see hand-pulled rickshaws of the colonial past as well as the newly introduced Volvo buses on the road, not to speak of gleaming luxury sedans that glide by every now and then.
Since all of them share the same road space in a city that has the minimum road length among all the Indian metros, it is no wonder that at certain patches the traffic moves at a pace that would shame even the snail.
For a while there are talks to phase out hand-pulled rickshaws altogether from the city, but once again given the pace things move here it’s no wonder that it hasn’t happened thus far.
