Depends on which ones, though. And there has been a ton of investment in public transit systems, so its likely going to be a very different place after all these systems are built out.

India has 63 out of the world's 100 most polluted cities: https://www.ndtv.com/india-news/delhi-is-worlds-most-pollute...

Most large cities in India are extremely polluted, and the smaller ones aren't necessarily any better. I have been all over India, over 15 states and union territories. Even the cleanest Indian cities I have been to (e.g. Chandigarh and Puducherry) are filthier than a regular city in other countries I've visited. It will take massive overhaul of garbage disposal and recycling infrastructure, as well as a massive cultural shift in how we treat our public spaces to overcome our enormous pollution problem.
