A few points:

1. I mentioned safety statistics that originally came from the NHTSA
   that showed just one car of the top ten as having a passenger-side
   airbag.  In contrast the driver-side statistics had eight of ten
   with airbags if I remember right.  That formed the basis of my
   statement.  I mentioned that the passenger-side statistics might be
   skewed because few cars currently have passenger-side air bags.

2. The passenger does not accellerate over that distance, he continues
   going the same speed he was before the car stopped/slowed, and
   *that's* only true if he wasn't wearing his seat-belt.  If he *was*
   wearing his seat belt the longer the distance the better the
   decelleration since it gives the belt stretching distance.

3. NHTSA statistics show that airbags have relatively little impact on
   whether or not injuries occur, but major impact on the extent of
   head injuries.

One more: passengers in the rear seat(s) who have only lap belts have
a higher incidence of back and neck injury than those wearing no
restraint at all.  It seems that hitting the front seat with your head
while scissoring forward is not particularly healthy.  A shoulder belt
in the back seat is a necessity IMHO, and I'm very glad to see that
most new cars have them.
