Seems weird that apple is willing to give up control over hardware and collaborate with the auto manufacturers. I'm sure the initial implementation of ios in the car will be awkward and hideous, very un-Apple. I'm guessing they see the potential of the "connected car" and are making sacrifices to make sure iOS is a part of it.
But what happened to all those patents about on-screen tactile feedback? And wasn't there a small company they bought that had imbedded physical knobs on a display screen?
I think Apple is going to control the software and push it toward Siri interaction. So the hardware isn't going to be used.
The tactile feedback is coming for the iPhone. I doubt it will feel like knobs on a screen, but it is supposed to do something. But this device is not going to be designed for you for reach across to the dash board and touch something. The driver will be expected to use on steering wheel controls or voice commands.
