The system (which we really hope is called “Gloogle”) takes the opposite approach to pedestrian airbags by using an adhesive layer installed into the hood and front side panels of the self-driving cars. This sticky layer would be protected by a thin coating designed to break open on impact. In the unfortunate event that the car collides with a pedestrian, the force cracks the coating, exposes the adhesive and holds the person firmly onto the front of the car, avoiding the secondary impact they could suffer by being thrown onto the road or into another object.
