I get a little bit worried when I read that they want one platform for everything, the security needs of different systems are too different. I'd say a modern car needs at least 3 separate systems: A low level system for all critical features, this should be coded as safely as possible and run on a slow almost unbreakable computer. A selfdriving features module, doing all the computations that are too intensive for the low level system. The low level system must be able to detect malfunctions in this system and act accordingly. An infotainment system, just assume that it has been hacked when designing the other systems. It should be simple to prove that this system cannot take over the rest of the car.
