Volvo has created a pedestrian airbag !

Most cars have airbags to protect their passengers. As such their located on the inside of the car. Volvo has come up with a new airbag that protects pedestrians and is located on the outside of the car underneath the front hood. It is meant for cars driving in cities where there is heavy pedestrian traffic. It operates at speeds of 20-50 km/hr (about 12-30 mph).

The car has sensors on the front that detect a human form and this causes the airbag to deploy. It helps protect the victim in two ways. First, it lifts the front hood to give more space between the person and the hard parts of the engine. Second, the actual air bag covers and creates a cushion over the lower part of the windshield.
