You are correct as to why you had to do that with the Quest. None of
those things apply for the Nüvis. Contemporary Nüvis are, to be honest,
nearly as powerful as the laptops of even a couple of years ago. They're
more than powerful enough to do the job independant of computers for
eveything short of map and firmware updates. Most people have a couple
of examples (edge cases, really) where in some exact circumstance, they
might have knowledge that the unit doesn't and can handcraft a better
route to some particular part or place in their area. But that doesn't
mean that the units routing is bad, only that the human being knows
better sometimes. And (hopefully) that is a circumstance that will
always be. When humans forget that they are smarter than the unit
sometimes is when we get the cases that we laugh at: some bozo with an
RV that gets stuck under a low bridge, or tries to drive down a river,
or through a pedestrian walkway. That includes things that change, too:
if a road is closed, the human knows to follow a detour. If traffic is
jammed up, a human can deviate from the plan.
This is where the strength of the routing GPS actually comes in, though.
It's not an indication of a failing in the GPS, because a carefully
hand-built list of turns can fail in exactly the same way. However, the
GPS can see that you've turned off it's path, and will try another means
of getting you to your destination. Sometimes, the new path will help
immediately. Sometimes it won't. Human overrides again, and the GPS
again compensates, presenting yet another plan. Eventually, human and
machine work their way past the problem and eventually both end up where
they were going.
And isn't that the point, most of the time? Getting to your destination?
If you already know what roads you want to take, why are you asking the
machine to navigate in the first place? Let it be just a moving map in
that case.
