I like the analogy. To carry it a little further, the CAD operators may be
driving right away in a new city, but they will become lost very quickly. It
is the CAD Designers that know the territory, the local rules of the road,
 the best radio stations, and all  the speed traps and the shortcuts when
there's a traffic jam up ahead. Those Operators are usually content to sit
in traffic, humming to themselves  :-)

<partial clip>
I always draw the following parallel : you can put 90% of the (western)
world
polulation on a plane to any city anywhere in the world, and ask him to rent
a car, and I'm sure that 99% of them will be driving within a quarter of an
hour after they've picked up the keys.  Maybe they won't know how to operate
the radio, but they surely will drive, and the EXCELLENT drivers (read : PCB
designers) will drive (design) BETTER (boards) than the others ...

How come ? Because cars have a standard user interface for 90% of their
functionality, and CAD systems have not. And why's that? Beause designers
don't spec that ... and when they would have over the years,  they would
have driven the "CAD-operators" well into extinction ...
