A touch screen is pure evil and stupidity and the product of grey old men dictating their products: "We NEED touch, build it in!"
Thing is, roads are bumpy. G-forces make your extended hand go all over the place. A touch screen in a car is pure stupidity. You want to rest your arm and take control of ONE single controller, either an Apple-like quality touch pad, or a knob you can navigate and press.
They'll get there, eventually. When those fossils die.
