A car key that prevents teens from talking on cell phones or text messaging while driving has been developed by University of Utah researchers.
The Key2SafeDriving system includes a device that encloses a car key. The device connects wirelessly with the user's cell phone via either Bluetooth or RFID (radio-frequency identification) technologies. To turn on the engine, the user must slide the key out of the device or push a button to release it. The device then sends a signal to the driver's cell phone, placing it in "driving mode" and displaying a "stop" sign on the phone's display screen.
