Really? I'm impressed -- if I were writing that, I'd be stumped about how to figure out if the phone is being used by the driver or by a passenger. And if it's the passenger, and you disable the phone, they're going to be pissed!
And what about that one time somebody gets abducted and the kidnapper forgets to take the victim's cell before tossing them in the trunk, and they die because their phone wouldn't let them call 911? Samsung's new ad will be "I'd be alive if I only had an Android phone!"
It’s all about nanny-state power.
Screw’em.
