"...Franz von Holzhausen, can barely contain himself as he talks about the design of the Model S. “It’s like the leap of faith Apple (AAPL) took with the iPhone,” he says, explaining why the car has a touchscreen instead of the usual physical buttons."
This is monumentally wrong. Touch screens succeed on a phone because a phone is a portable device and the touch screen is lighter and smaller. Physical controls are preferable for humans because they model the physical world to which we've adapted. In a car, you need to use the controls without taking your eyes off the road. This means location by feel is important. A touch screen can't provide that.
It seems the entire design world has this backwards, include appliance manufacturers. I hate the buttons on my oven.
