Can't vouch for all car architectures, but in most cases the head unit is QM and safety domains are usually segmented from each other. So even if the head unit talks CAN (it needs to get car data somehow) it will only communicate with the rest of the car through a gateway that will not allow it to take any dangerous actions.
