It is estimated that around 17 percent of all accidents with personal injuries in Germany are rear end collisions in longitudinal traffic. The main causes of such accidents are driver distraction or inattentiveness, and driver misperception where a driving situation is misjudged. Forward Alert operates at speeds between 7km/h and 180km/h. A decrease of over 25 percent for both slight and severely injured occupants in front to rear collisions is thought possible in cars equipped with Forward Alert. If all cars on the road were equipped with such a system, this would be equivalent to Forward Alert providing some measure of protection in accidents where, currently, around 8,500 people are severely injured and 63,500 are slightly injured in EU 27.
