Pontiac 2009 G8 Owner's Manual page 11

Put someone on it.
Get it up to speed. Then stop the
vehicle. The rider does not stop.
The person keeps going until
stopped by something. In a real
vehicle, it could be the windshield...
or the instrument panel...
Seats and Restraints
or the safety belts!
With safety belts, you slow down as
the vehicle does. You get more time
to stop. You stop over more distance,
and your strongest bones take the
forces. That is why safety belts make
such good sense.
