A large part of that is "savings on fuel"

Yeah that’s a Tesla trick to make their cars look cheaper than they are. It’s deceptive. When I buy a gasoline power car, I don’t figure the cost of gas into the purchase price of the car.

It also wrongly assume that you can charge it at home. I only have access to street parking in London. I would need to register to various charging provider in order to be able to keep a car reasonably topped up without having to go to the supercharger at the beginning of a journey.

The price of the monthly subscription(s) alone is a very significant proportion of my gas consumption (I'm a leasure only driver, I do maybe 5000 miles per year, the bulk of it is done in 4 to 5 road trips)

In Spain, the standing cost of a residential electricity contract that is sufficient to charge a Tesla (i.e. above the regular Spanish 3000W default contract) is similarly a significant portion of the gas price.
