University of Utah engineers developed a new Key2SafeDriving system to prevent teenagers from using cell phones while driving and to reduce cell phone use by adult motorists. Each driver of a car would have their own special key. When the key is extended from the wireless device (sample shown at left), the device sends a signal that displays a stop sign on the cell phone (right) and prevents it from being used to make calls or send text messages. For adult drivers, the system prevents texting and allows calls only on hands-free cell phones. Parents can control the system from a computer. Here, the screen displays safety scores collected by the system based not only on cell phone use, but on driving speed and traffic violations tracked by Global Positioning System satellites.
