A satellite-guided back-seat driver? A new system combines real-time navigation with radar safety tech to help a driver decelerate or brake into curves
Nissan has made another stride toward that strange but often-promised future: cars that drive themselves. A new system set for release in Japan links information from a car's real-time GPS navigation with existing radar-guided safety tech to help drivers make smooth turns on curvy roads. The Navigation-Cooperative Intelligent Pedal uses GPS mapping data to detect an oncoming bend, then strategically decelerates or applies the brakes. Here's how it works: When the nav system indicates a curve is looming, the accelerator pedal physically moves upward. Then the system activates the brakes.
