>We absolutely want to remotely control cars at some point, how else will you send a self-driving taxi to a customers or "ask" a car to comeback to the garage for a recall on the underlying hardware or for general maintenance?
Who is this "we"? You might, but I don't.
That's a disaster waiting to happen.
What's more, under the circumstances you describe, there's no reason such vehicles need to be internet accessible. Or have we forgotten that communication doesn't require the internet?

What kind of remote communication these days doesn't require the internet?
Text messages?
Special short range base stations with 56k modems?
>What kind of remote communication these days doesn't require the internet?
Pretty much any low power radio application (CB/HAM radio, key fobs, walkie talkies, POTS lines and dozens more), or higher power (although those require FCC licenses) don't require the internet.
Besides, I'm referring to the software that makes the vehicle operate. That software/system should never be exposed to remote sources. Otherwise, you're pretty much begging to be locked in your car and taken on a joyride which ends with you rolling off a cliff.
Your car is not going to have a Ham license, and I already mentioned POTS; do you really think having your car sit close to a special phone-based communication station is the answer? Key fobs and walkie talkies and LoRaWAN do not have enough range to fully enable this kind of use.

If hacks while driving are your concern, you could have the car isolate from the internet when the key is inside it and/or someone hits a stop button. If hacks before driving are your concern, I don't think any of your suggested radio applications are safe either. And I don't really see why half of them are better than an internet connection in the first place.

The difference is that there aren't 25,000 (conservative estimate) people looking to hack/scam/destroy stuff on local radio channels.
Which means that someone would need to target me specificly, not run across the poor/no security on the internet link from my car while scanning the 'net.
Besides, the car proper (ICE/electric motor, steering, brakes, etc.) and the software that runs it shouldn't be accesible by anyone unless they have both physical access to the car and a reasonable amount of security (key fob, password, etc.) to be allowed to muck around with the car's operating software.
Infotainment systems, sure. But those need to be on separate, air-gapped hardware.
A valid opinion, but not what I'm trying to argue for/against. I'm saying that if that remote access is your goal anyway, internet vs. not-internet doesn't feel like it has a big safety impact.
