Last fortnight, when the world’s richest Indian Lakshmi Mittal visited Kolkata, the city of his youth, he was thrilled to see change. Mittal told the media that the biggest difference he saw was the many flyovers dotting the city skyline and “disciplined traffic”. This is great progress, he told journalists, who promptly reported that the tycoon had given the city’s road and traffic management a big thumbs up. I was also in Kolkata that day. But all I could see was lines and lines of traffic, belching black smoke, honking madly.
