The recent proposal to allow the National Highway Traffic Safety Administration to regulate the use of smartphone apps by drivers in moving vehicles is a step in the right direction. The reasons that distracted driving behaviors are increasingly being regulated and often banned are twofold: First, more research is showing the severe danger associated with using phone apps of all kinds while driving; and second, more and more serious accidents are being caused by such behaviors. While preset navigation apps are in themselves not dangerous, the misuse of them while driving is just as dangerous as more irresponsible behaviors like texting.
