One (speculative) way to look at it, is that with ICE cars, there is this conceptual division, for the manufacturers or the customers, between the propulsion, and all the electronic gadgets. It is understood that the engine is what's essential but many of the electronic gadgets and features will probably die over the years and the car will remain driveable. I bet that with a Tesla, because it's electric and there's no dividing line in everyone's minds between systems, that it will fail according to the usual pattern with electronics, and the motor and batteries won't be isolated from that.
