He's not saying that cars shouldn't be updated... But that OTA updates are a problem. They're saying that it should be a drive to the dealership to do an update. I would go a step further and make it possible to have it opt-in for car manufacturer to send out cd/usbs to update firmware.
Offline updates are generally fine and not super susceptible to general hacking. OTA on the other hand... that's a massive risk for a reward of.. slightly faster fix times?
If it's a safety system, it might be "have the car taken to the dealership on a flatbed truck". Also, some people don't live near a dealership.
Like it or not, all modern cars are connected - for the maps if nothing else - and if a car is capable of an OTA update, I say do it. I don't see how a dealership adds anything other than cost which will always discourage updates from being made at all.
And I actually think physical updates are easier - connect a laptop to the ECU, and you're done. It's generally only OTA updates that use code signing/etc.
Carplay and Android Auto are better than any other in built infotainment shit. I do not see this as valid. Nor that does mean that firmware on the car should be writable from those systems.
Thus why I said...
Then any dick or harry can do it on their own.
But honestly whenever I say "dealer" I really mean any repair shop.
