It would hope the UX would be completely optimized for a heads up display.

For example, I would love a virtual pace car that I could just follow. I would slow down when its virtual brake lights went on, I would switch lanes when it did, and I would prepare to turn when it put in it blinkers.

This would require Google Glass to be completely integrated with the car's radar-based collision avoidance system.
