Unfortunately, there *are* people out there who seem to blindly follow
instructions from their GPS navigation system and don't really do much
in the way of thinking....

Well...this might work.

If you do find them, please let me know, because I'd love to see
exactly how the tagging is done, and how routers handle it.

That's exactly what I intend to do.  I wanted to get a discussion
going here, first, with ideas, so that they'd have something to think
about.

This is a point worth remembering.  Every couple of years there's a story about somebody who
drove his car up a goat track with nowhere to turn around because he blindly followed his GPS.
Or who drove off a cliff, same reason.

The newspapers usually conclude that this is a fault in the GPS software.  I'd bet that in most
(probably all) cases this is a fault in the operator.  Many in-car GPS units have three modes of
operation: shortest route, fastest route, and walking route.  Guess which one of those three leads
to being stuck up a goat track or driving off a cliff.  PEBSWAG (steering wheel and GPS).

People DO blindly assume the GPS is right.  Even when reality appears to contradict it.  So it's
a good idea to ensure that the GPS is right.  Especially when lane reversals are involved.
