[Tagging] Highway mistagging ... again

I think part of the problem with the highway=track description is that even
when you are there on the ground it isn't always clear what it's being used
for. They are often two ruts in the ground disappearing of into the
distance with little else to go on. If you then look at aerial imagery you
may see that is goes to a single house and re-tag as driveway or that it
serves multiple buildings and guess at whether the buildings lean towards
highway=residential, highway=service or highway=unclassified. It's easy to
say "primarily agricultural or forestry" but this is often rather difficult
to verify.

There is then a separate problem in that OSM-carto, the default 'check that
it worked' renderer, doesn't render road surfaces or tracktypes for
anything other than tracks. This discourages the 'proper' tagging for those
who want to tell at a glance how likely they are to get their car stuck or
how likely it is that they will be able to do a three point turn if there
are obstructions.

Tangentially, I have always found the tracktypes a little difficult to
apply if you don't have the type of soil depicted in the examples. Some
ground tends to get "lumpier" rather than softer if you keep using it
without improvement.
