From what we've seen of car software (e.g. Toyota accelerator control), it wouldn't surprise me if the electronics system is tightly coupled to both critical functions and specific hardware. Looking forward, my hope is that electric/self-driving cars will be more like modern PCs or those heavy-duty e-juice vaporizers that people have today: composed of well-understood parts that connect in compatible ways.
