Android and iOS auto, do you want these systems to attach this easily to the car?

Safety critical CAN bus messages should be signed.

Android and iOS auto don't have access to the CAN bus that can control steering. They may have access to a physically separate CAN bus that controls the entertainment system and air conditioning. There are normally multiple buses in a car.

Is there a legal requirement that the CAN buses be air-gapped?

Then you have to certify signing mechanism so that braking works even if cosmic ray ruined brake pedal control unit, and that is half sane and half stupid.
