Voice seems to be the best and safest user interaction for vehicles. If the voice software knew the car was in motion or at a difficult intersection perhaps it could change it's tone and sense of urgency. It does make me think if there will be VI(voice interaction) designers in the future.

I find voice controls extremely distracting, mentally. It takes your focus off the road just as much if not more, I believe. Plus, I always have to repeat myself a bunch because I believe they are programed to recognize a man's voice.
