Fredgroves & Booth11 - totally agree with you.
I have no problem using flat, responsive, intuitive, touch screens when the care is static. It's when you're on the move that they're troublesome and downright dangerous. Many on here have said how distracting and dangerous operating menus via the central flat screen can be whilst driving.
I'm no expert but surely, in the name of progress AND safety, we have to use a combination of heads-up, flat screen in binnacle (like the new TT) and voice control. That way we should be able to access any technology in the car without having to mess around with poky, unresponsive centralised flat screen consoles - which are dangerous!
So, where does that leave gesture control. Well unless the technology can read facial gestures, or use thought control [see Firefox movie with Clint Eastwood] it still leaves us taking our hands off the steering wheel to give the car a command. No thanks.
