I was thinking more along the lines of the fact there are
demonstrative loss of performance characteristics when
operating over a specific aircraft's gross weight limitation
and probably a much higher risk of accident versus than
that of operating an automobile at a speed higher than
what was arbitrarily chosen by the government without
regard to the specific vehicle type.

Well, quite, but that's a conclusion that *you* are coming to, and in
doing so, you are ignoring the rules. And yet if someone comes to a
different decision and decides that, for example, being 5% over-gross
is safer than being 15% over the speed limit, that somehow makes them a
slippery-sloper who will suddently start to break other rules, while
the speeder's judgement as to what rules to follow is considered
without such dangers. Doesn't make sense........
