Cars equipped with the latest safety technology already warn drivers about oncoming cars. Japanese automaker Toyota Motor Corp. has developed the world’s first system for detecting rear-end collisions before they happen. A radar installed on the rear bumper detects vehicles approaching from behind. Sensors in the front headrests detect the position of the driver’s and front passenger’s heads, and shift the headrests’ position to reduce the risk of whiplash injury. If a car gets too close hazard lights start flashing warning the driver. In addition to cars it can also detect pedestrians also. The system uses a newly developed camera called stereo camera that can detect information on three-dimensional objects, in addition to the more common radar. An infrared projector in the headlights supports nighttime visibility.

Like the Automatic parking Prius this new system will be initially offered in Japan with Lexus LS luxury model in September before making it to the US and Europe.
