I've had friends maimed by drunk drivers - let me just get that out of the way first.
I honestly wonder what it is about texting that has finally gotten people's attention when it comes to distracted driving. I've seen people eating, chatting (while looking at the passenger) and doing all sorts of other things (including self gratification while a Hustler magazine was open on the steering wheel) and nobody's said much.
In time, this will pass as more and more Autopilot features come into play. Nothing will stop this. It might not even be laws that are the deciding factor. My early prediction was that INSURANCE companies will drive the adoption of these technologies. They'll offer you a discount if you'll purchase software that never gets drunk, never gets distracted, never gets sleepy, never has an argument with it's wife, never gets depressed and never has a crippling health issue while driving.
