Mercedes-Benz is introducing new accident-prevention technology aimed at making cars safer and more "intelligent" than ever before. Pictured: a computer-generated crash simulation. Mercedes-Benz on last Friday issued a report that details its plans for "intelligent driver assistance systems." In short, the German automaker said a new generation of technologies, including "video-based assistance functions," is on the horizon that will increasingly help drivers operate their vehicles with an eye toward preventing accidents. A new Mercedes lane-changing system uses six radar sensors that monitor the area behind the sides of the vehicle to help with blind spots. If a vehicle is in the car's blind spot, a red warning light will appear in the side mirror. The system then sounds an alarm if the driver doesn't notice the red light and even turns on the blinker by itself in advance of the driver changing lanes.
