The mere CONCEPT of a car manufacturer being able to push UI changes to the car that I drive is equally disgusting and terrifying. I will never, ever own a Tesla or any similar garbage.
Not sure why it's the problem when update is an improvement.
Lets say tesla pushed an update that let me schedule start charging and stop charging at a certain time. That saves me $600-800/a year.
Or a special controls for noise of the car for kids.
There are good examples and bad. Last tesla update is not good, even it's not horrible, and let you customize many things.
Whether a particular person objects to a particular update does not affect the validity of a general rule that safety-related changes should require oversight and/or consent. Those rules exist to protect all users, and even other drivers on the road who could be affected when unintended actions or unnecessary distraction cause an accident. Maybe you haven't been burnt yourself yet, but regulating such changes is what keeps you from getting burnt next time.
