I change my tires every 20,000-25,000 kms

for me it means every 3 years

my car runs on LPG, which is half the price of gas

Never ever done any particular kind of maintenance in over 10 years.

You can buy 6-7 brand new "my cars" with the money spent on a Tesla.

Yes, it's a cheap car, I chose it exactly because it's cheap and robust, I use it in a city, I park it on the road, there's no need for a >45k car, I would argue it's borderline stupid to buy a very expensive EV to drive it in a city.

EVs are expensive by default, their TCO might be lower in perfect ideal scenarios, until you run into an issue, most of the cost is due the complexity, non-EV cars are much much much dumber and simpler.

You can't independently fix an EV, there's no way.
