I think you are imagining this.  If you run into an obstacle that is
100mm (4") or higher, the wheel will stop and the bicycle will
overturn.  Your scenario of riding up the back of the car is
apparently based on imagery rather than fact.  There are enough
examples of bicycles running into curbs lower than the bumper of the
VW who did an end-over.

Hypothesizing will get you nowhere.  Had you really experienced that
some time in your bicycling experience, you would know that the rider
flies over the bars.  That you strike the top tube with your crotch is
an old bugaboo passed on by imagining souls.  The same is true of
striking the handlebar stem when going over the front when striking an
obstacle.  It doesn't happen that way.

That may be your experience but not that of most bicyclists who
actively ride.  You had best not argue that case with most tourists
and racers who ride instead of hypothesizing about it.
