I never thought SUV stood for SPORT Utility Vehicle.
 I always understood it to mean SUBURBAN Utility Vehicle.  The Suburbs is
where you see most all of them, not doing sports, but usually sucking down
petrol going to music lessons or shopping or headed here and there on the
freeways..

  In the country or in 4wd territory, pickups seem the vehicle of choice..

As an acronym(sp?) "SUV" works pretty well if you think of the "S" as
standing for Suburban..
   As an aside, it may be that the original SUV was the Chevy Suburban of
around 1958...Very like the today larger 'Murikan SUVs, but a bit smaller
and certainly quite different from what was being built by anyone else at
that time.  Kinda like a huge Station Wagon built on a truck chassis and
with lots of ground clearance, but simply awful to ride in.  I remember
riding in one that a pal of my father owned in the '60s, down a long
washboard road in Montana to hit a fishing spot they knew...It must have
been awful if I remember it still to this day..
