This comment actually got a laugh out of me. I truly have no idea what would be feasible in a collision like this. Probably packing peanuts? Airbags on the outside of the car that deploy when a pedestrian is detected?
A more bizarre solution Google patented always stuck with me: A sticky car hood beneath an eggshell coating so that a struck pedestrian would stay on top of the car instead of falling and hitting their head or being run over [2].
