> Seems to me that this sort of thing would save at least as many lives as the incessant beeping that new cars activate when you turn on the ignition without fastening your seatbelt. I wonder what the net effect would be, considering the potential of drivers to be distracted by annoying beeping noises, or to condition themselves not to look out windows or in mirrors when doing so is more important than looking out the windshield. > Then again, maybe this is a terrible idea, bound to plague millions of drivers the way the seatbelt beeping does. I dunno. I'm just really sick of near-misses with idiots who are texting while driving. I'm not convinced that it's generally a good idea to outsource responsibility for safety to external devices, but if you're going to do it, in this case, it may be more reasonable to put the constraint in the phone rather than the car. It should be relatively trivial to restrict text entry when moving at high speeds on a phone with embedded GPS, and doing so would alter the behavior of the thing causing the distraction rather than the thing you want drivers to pay attention to.
