What people really need to do is the actual calculation, instead of saying things like "the Tesla will make it up over its lifespan". Will it, really?
The difference between a model Y and Corolla is, what, $10k-15k? That is a huge difference to make up. Most of the maintenance requirements a ICE has are required by an EV, too (less oil changes). Parts are way more expensive on the Tesla than the Toyota.
Oh, and do you think that governments are going to just let EVs operate on subsidized electricity forever? No, they will directly tax it in the future. Meanwhile, gasoline prices could decrease over time as the world transitions to greener sources. After all, have to pump the oil (increase supply) while it has value.
TL;DR People who buy a Tesla to "save money" are likely in for a shock.
