Couple of inventors in the U.S. are bringing a product called Key2SafeDriving to the market. The technology in the device blocks the cell phone of the driver so that he/she cannot talk or text until the destination is reached. The device is created by university researchers in the U.S., Xuesong Zhou and Dr. Wallace Curry. Though the cell phone of the passenger won’t be blocked. If there is an emergency call, the phone will ring differently. This technology is certainly useful specially when there are a number of road accidents due to the use of mobile phone.
