There is also a big difference in the importance of reliability. Half the people I see with iPhones older than a year have broken screens. But with a car, you can't engineer it to last for two years and then expect the owner to scrap it and buy a new one. For all the talk of AR, shiny UX etc, keep in mind that a car has to retain at least some resale value for at least ten years, preferrably closer to twenty. Otherwise you'll be left with a lot of angry customers. Planned obsolesence is out of the question.
