"develop a mechanism or app that would automatically disable any handheld's “driver distracting functions” while in a moving car"
A suggestion obviously made by a bureaucrat with no children. Long car journeys without a handheld distraction? What is this, the fucking 1970s or something? You develop a mechanism that means your gadget doesn't work when my car's moving, all that guarantees is that I'll buy your competitors' gadgets instead.
