I like travelling, especially to new cities. My visits are typically not very long. In the past two years, I have been to Beijing, Shanghai, Sydney and Tokyo. But each city brings forth a different charm. Seeing them I realise how long the Indian cities have before any of them can be called as a world city.
One of the things Indian cities lack is Dimension. Look at New York, London or Tokyo. They have as much of an existence below the ground (subway) and above the ground (multi-level roads and freeways) as on the ground. Indian cities, by contrast, are in Flatland. Delhi and Calcutta are making efforts with the metros. But there is still a lot more work to do.
