I’m trying to discern your point. If it’s about cars having a data connection then my point makes no sense, obviously. But your comment was in response to someone complaining about “remote control” which is just “remote unlock” (that’s all Tesla does remotely in the context of GGP). So that’s how I interpreted your response.
Most new cars do have a constant data connection though, including directly to the main CAN bus, where it has been proven that people can steal your car without a key or even disable it remotely. You shouldn't buy any of those cars either...
