The Centre has been evaluating the concept of a protective headband for car occupants. In about 44 percent of cases of occupant head injury, a protective headband, such as the one illustrated, would have provided some benefit. One estimate has put the potential benefit of such a device (in terms of reduced societal Harm) as high as $380 million, compared with $123 million for padding the upper interior of the car. This benefit derives from the fact that in a crash, the head strikes objects other than those that could be padded inside the car.
