Disable All SmartPhone Functions While In Motion (driving)

The threat of serious bodily harm or death justifies disabling all functions of smartphones at a velocity over 10-15 MPH. And yes, this would apply to the driver or a passenger in a car or in public transportation. I lean libertarian and the goal of staying alive does not conflict with my political philosophy. Smartphones are candy for the many ADD afflicted drivers out there. Defensive driving cannot fully protect us against the negligent behavior of smartphone users. (in response to this article)
