The person keeps going until
stopped by something. In a real
vehicle, it could be the windshield...
or the instrument panel... 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.
