The NHTSA has taken another step forward to combat distracted driving by proposing voluntary guidelines for automobile manufacturers to help minimize in-vehicle driver distraction.  The goal is to balance the technological innovation that consumers want with keeping our roads safe and drivers focused on driving.  The focus is to limit secondary tasks (communications, entertainment, and information gathering etc.) that the agency believes will interfere with a driver's ability to safely control the vehicle.
