Yet even Tesla does a rather bad job at this — they consider it to be a modern electronic device and ignore the wheels. OTA updates regularly change the UI in a way that is difficult and dangerous to learn when the wheels are spinning. Even when familiar with it, the very basics are hidden in menus and cannot be used without looking away from the road for longer than is safe.
Car companies: make your car software simple, reliable, and boring. You may well need to spend serious money doing this, but the goal should not be for it to be fancy or to feel extremely modern.
(With the latest update, turning off the seat heater is buried in a menu. I still haven’t figured out how to efficiently dismiss overlay apps that are covering the map. It used to be fairly obvious.)
