Researchers at the University of Utah have developed a new device designed to prevent drivers from talking on their cell phones or sending text messages while operating a car. The Key2SafeDriving technology, for which provisional patents and licensing have been granted, is a device that’s coupled with the car’s ignition key. Once the car’s engine has been started, K2SD sends a signal that blocks the driver from dialing out or texting using his or her cell phone. It also blocks incoming phone calls and text messages.
