If impact is supposed to include a toughness factor, it should really be based on DR, not hit points. In any collision, there's a certain amount of energy which needs to be absorbed somewhere, and 'somewhere' is usually the softer object.

Of course, collision damage should also be based mostly on the hit points of the smaller object; a human getting hit by an aircraft carrier moving at 10 mph is not going to be significantly more hurt than one hit by a truck moving at 10 mph (this assumes the human doesn't get caught between the vehicle and a solid object); in either case, it's basically a 10 mph collision with an essentially immovable object.
