Re: Touch screens
While I agree and hate touch-screen, it's not as if the prior model was a panacea.
My previous car had a vent open/close button which DID NOTHING until you ALSO turned the FAN on, and had no indication of such.
Most cars have a hot-cold temperature dial which allows you to mix hot engine coolant with your cold air conditioner output, with little or no visible indication in the non-extreme cases.
Both are issues an electronic control system would be smart enough to prevent. And while you can have mechanical inputs to an electronic system, there's rarely any way for them to provide feedback when the computer overrides them (i.e. motorized dials), which is a problem in itself. Electronic push-buttons with LED indicators are a reasonable compromise, but I have yet to see a vehicle where that is used for ALL the controls.
