I saw this article about new car technology. Acually, forget the technology, just imagine how annoying it would be to hear “car approaching on the left” or “watch your speed” every few seconds.
Japanese carmaker Nissan has said it will mobilize 10,000 drivers in a 30-month experiment to develop an "intelligent transportation system" that sends wireless messages to passing cars.
"Car approaching from left" and "School ahead. Watch your speed," are two voice messages which drivers will receive through the system which uses information obtained from nearby vehicles and roadside optical beacons.
