Just visited Mumbai last weekend, it has somehow gotten worse over the last 5-6 years. Every 3rd or 4th road is either under construction or unusable.
This girl from bumble legit defended Mumbai being safer than other metros literally after an illegal billboard fell on innocent people.
The "spirit of Mumbai" is Stockholm syndrome, most of the victims/residents just don't know it or have grown numb to it.
Every year people die on local train tracks and platforms, no one cares enough to do anything concrete about it.
Mumbai and Bangalore are both spiralling towards being borderline unliveable. Delhi NCR too to an extent. But the unfortunate reality is that they are economic hubs, hence people are forced to work there.
Decentralisation is the need of the hour, tier 2 and 3 cities must prepare themselves for reverse migration in the next few decades. I'm planning the same for myself if all goes well. It's not worth slowly dying in poisoned cities.
