For 2021, sure it is. Context matters. There’s no way in any mythical place that Tesla announces anything more for India next year. Too much already on their plate and bigger fish to fry first.
The biggest problem with importing cars in India is taxes. Yes they will likely start in India next year and will sell plenty. I have a few friends back home who are itching to buy a Tesla in India. I was chatting with one of them just last night as his current car got flooded and he is in the market to buy a new car. He knows that ICE will be dead soon but has no EV options to speak of. So ICE it is for now for him.
The import taxes will mean that a model 3 that is priced at 45K USD will likely have a OTD price of $90K or thereabouts, yes you pay a lot in taxes. The taxes are reduced if Tesla can setup an assembly plant(I believe merc and BMW already have assembly plants in India) and finally can provide China like prices once they have a local manufacturing plant. Tesla cannot achieve price parity or volume sales until they have a MFG plant in India.
