GURPS 4e collision rules are broadly wrong in that they base the
collision damage on the mass of the larger vehicle. The fact is, a
human hit by a one-ton compact moving at 20 mph is not going to be
significantly less hurt than one who gets hit by a forty-ton semi
moving at 20 mph (total collision energy, assuming a 150 lb human,
is about 6% lower).
Good point. I would use collisions only when both object where of
nearly the same mass--enough so that both their velocities would be
affected by the collision.
If one object is so much more massive than the other that it's
velocity is effectively unchanged, then I would treat the smaller
object as taking "falling damage". I'd use the relative velocities of
the two objects, then figure damage as if the smaller object had
fallen from a height high enough to achieve that velocity.
