What about using NFC to disable anything but GPS or hands free calling?
How about using the grey goo between your ears, and drive the damn car?
Hands free does NOT make it better. Your brain is still occupied on things 'outside' the car.
I'd argue against that. Talking on the phone (handsfree) doesn't require much more concentration than, say, singing along to a song, listening to a podcast/audiobook, or talking with a passenger. And if something happens ahead of you that requires your attention, there's nothing preventing you from focusing on the road long enough to deal with whatever situation. If your eyes never leave the road and your hands never leave the wheel, you're fine. If anything, having the stimulus of music or conversation in the car keeps you more alert and less likely to space out for long periods of time, or worse, fall asleep.
