My gut says that the performance in a vehicle collision will probably bring the head to a halt...
Presumably, the impact would cause the pedestrian to fly back in roughly the same direction the car was moving during the impact, rather than come to a complete stop. That said, I don’t really know enough about the tests to know if this would make a difference in efficacy. Could you link the exact data you received?
The data is posted above, unlikely to get around to Dropboxing it so I can link (as it was from an email). I agree with you re body movement in a vehicle collision. However, at some point your body would stop. If your head hit something while your body was in motion, thr impacted object would likely have enough strength to bring the head to an abrupt halt. (Contrast with a knife being punched through paper mache—I would expect the force on the lnofe to be much lower than if hitting concrete, as it would go through the paper mache without much velocity change.)
