Look at the post below:
Yeah those 'feel-good-comments' like "Chittagong is not even near to tier 9/tier 10 Indian cities" have posted numerous times, even I have conceded, don't be too modest, say Chittagong, Dhaka are not even near to your villages! Though it's a different topic that those villages don't even have toilets.
If you never heard of Chittagong, I won't blame you, history of Bengal must have been neglected in Indian text books to make room for the detailed North Indian history. I'm sure you never heard of people like Surja Sen, Pritilata Wadeddar etc. It's not possible to accommodate the history of entire India in those text books.
And no I don't think Kolkata would have more such cars because Chittagong is home to some of the oldest and largest conglomerates in Bangladesh and in some cases, entire South Asia but Kolkata is not. The IT boom may have contributed to the economic growth but most of the IT specialists are heading for other cities like Bangalore, Mumbai, Chennai etc. If you don't want to visit Chittagong, that's your loss.
