Nissan showed technology that protects both walls from cars, and drivers from their own
stupidity lack of judgment. Sonar devices in the front and rear of the car detect hard obstacles. If the system decides that the driver is about to hit the wall, the computer cuts the gas and applies the brake.
Yesterday, Nissan was confident enough in its system to load journalists into a car, which then was driven into a wall erected in the parking lot of a Yokohama soccer stadium. The computer prevented harm to car, wall and fourth estate. The system also should prevent low speed collisions in garages and during traffic jams.
The system will first be optionally available in the new Elgrand minivan, which will go on sale in Japan on December 13.
