The real reason it's not air-gapped is because it makes the package count lower, and manufacturers don't give a shit about owners' privacy or security.
How many things are adjustable in modern cars that are actually necessary to adjust? Having that many options is just piss-poor user-interface design. The only things that really need buttons and knobs are the parameters that have to be twiddled with while the car is running. The rest is offline config that could be done just fine with a touchscreen or a mobile app without causing driver distraction and getting people killed. And none of that has anything to do with physically separate data paths for ancillary functions versus critical controls.
