Electric cars can have even | more complex requirements. There is definitely a push for AI in cars. The closer to self-driving, the more processing power is needed. Also: electronic features are a lot cheaper than mechanical features. So there is a tendency to add as many of those as can be imagined. Features seem to be what sell cars. Also: processors are cheaper than wires. So sensors need to talk to shared buses, not simple wires. So each sensor needs something approaching a processor. I understood most things about my early cars. My recent car is another matter. I'm pretty sure it has a lot of features that I haven't even imagined. And it has a tablet-like control/display unit in the middle of the dashboard. Much of the interface seems too complicated to operate while one is driving. I guess I'll learn about the controls of my first self-driving car because I won't be distracted by driving it myself. Simplicity is sophisticated. It's hard to sell. Apple tries sometimes. Some AI that I'd like in cars: When I'm driving, I can often tell something is wrong by the noise or vibration or smell. AI could monitor all these signals and try to infer problems that might require attention.
