> Verizon, ATT, Tmobile and their APNs are controlled by the FCC, and any regulation can force vehicle traffic to be isolated if there is credible threat.

This response would *not* be soon enough. One response from a server, and the car could be bricked forever, explode/short circuit causing a fire, self-drive into the nearest government building, etc. A car is a huge weapon, especially when remotely controlled. This software could be pre-installed from the factory, with commands injected via side channels. I could imagine a hundred ways to do this.

> but, why would BYD or other nation sabotage its own future profits by bricking cars?? it doesn't make sense.

I'm precluding this situation with a background level of hostility between nations... they don't care about maximizing profit, but maximizing damage. It would be a government stepping in forcing this.

Good point though. My current cars drive just fine without internet - I would hope future cars would continue to do so, even if GPS doesn't work, can't find a charging station, etc. Otherwise, I'll be stuck with gas cars until the day they take my license..

The Mi SU7, a pretty competitive EV with Model 3, starts at around $30k (still a pretty decent price).
