I would rather see a different kind of mashup - install the Google Glass into the car. Put the camera on the rearview mirror facing forward, and install a small heads-up display to reflect off the windshield. This could be a lot more interesting than Apple's in dash iOS approach. Then you could use all the glass apps + features while driving, without having to wear the headset. From what I hear it will be basically impossible to use glass while driving because you have to look up and to the right to see the screen.
