Not least because this is why I wouldn't consider buying a Tesla. It feels too much like dealing with software: it isn't your car. It is Teslas car. And maybe paying a bunch of money for it means you can drive it, but sometimes, when you hit some corner case, it doesn't.
I've been a tech at a Ford dealership, and I'd say that the incidents which render the average Ford undrivable are far greater than the incidents which render the average Tesla undrivable.
The there are the massive privacy issues and the fact that you can't do anything about that: your car is spying on you. (I know consumers don't care enough about this in the US to elect politicians that take privacy seriously, but in Europe we do. Which is why Tesla is under scrutiny for not only collecting massive amounts of invasive data, but also for not being able to adequately safeguard the data they collect).
