Car manufactures have figured out a "universal interface" (buttons) as much as iPhone figured out touch screen. There is nothing universal about the iphone interaction except that you touch it, for example it doesn't have a back button which most other manufactures do. Behind that touch screen you have the same mess of buttons/sliders/dropdowns/checkboxes/toggles between different models, as in cars.
