This comment and your following comment seem to show a reluctance to accept EVs as solution. You haven't considered some major points:

1. "Import duties are high", "Direct import is not viable" - it's the govt we are talking about. They'll HAVE to ease the import to make it work.

2. Vehicles age; and they break down faster on indian roads. Current vehicles will eventually expire and open up space for electrics. no one is going to ask you to smash a new car.
