The point they're making is that this is coming and the groundwork is already being laid, both legally and technologically.
So they are basically claiming that something is a problem, even though it is something that's straight up currently physically possible (but someone who reads that statement without knowing the actual details wouldn't know that it isn't currently possible)?
Disingenuous at best. Especially given that the parent comment said none of that. They essentially mocked people who believe that it isn't possible, and when they got pointed out that it isn't actually physically possible right now, the response is "well, not right now, but look at future possibilities!".
I could see this being a "feature" of leased vehicles for example since you don't own it.
Tesla's should be fully functional currently, it's the self-driving that's a subscription.
that feature has existed for over a decade. Miss a payment and your engine can be remotely disabled.
