You don't need a software-free car (with all the complicated mechanical contraptions this then requires, like carburetors) to have a basic car that doesn't need updates. You just have to write software properly. This has already been done! Cars in the 1980s and 1990s all had ECUs running software, and they never needed updates just to keep the engine running. Later (late 80s and through the 90s) they added ABS brake controllers and SRS airbag controllers, all running software. They didn't need updates either. The idea that computers need software updates is just insane, and clearly fallacious. Cars worked fine without regular software updates for decades.
