Your average iPhone uses nowhere near as many parts and partners as even a mid-range car. Plus, the iPhone doesn't have to go through rigorous crash testing, pass environmental regulations, and deal with entrenched lobbies. The automobile industry is over a hundred years old. There are deeply entrenched players, unions, etc. that Apple would never want to deal with. Besides, profit margins on cars tend to be crappy, at least for anything with any mass appeal
