Usually, the smallest of roads are 'tricky passing', but actually if you in
enough of a hurry you don't have to stop and wait, but can drive half off
the road, or force the other driver off the road. In the few places where
walls/banks/hedges comes up to the road edge, then passing places have been
created every 100 yards or so. Personally I wouldn't tag each one, but If i
did i would either tag a node or make it similar to a small layby. Because
they are so close, usually it would be a waste of time to request the gps
device to take you to one, becuase you would have spotted one already,
either that, or the other car would become so bored of waiting for you to
check your gps that it would have reversed.

It can be averaged. If it reappears every year, but is so softcore that the
weather disposes of it, then I would tag it grade5. Roads may change over
the year as snow falls on them, and they are nolonger a road (pennines).
For the more hardcore tracks this isnt really true. I have had grade5
(wich is just grass tracks), tagged since late last winter, and they are
still there. Although the grass grew back in the late summer, the area was
left clear for access, and the clear indentation in the ground remained. It
is also a footpath. If the track wasnt there, then 5 or 6 fields would have
no access, so its definatly there.
Conditions change widely over a year on all surfaces not just tracks. Roads
in the Pennines (England, UK) can be covered in snow, and therefore are not
a road, but just snow...but underneeth the snow is still a road, wich
reemerges when the snow thaws. Therefore the anual average use of the way
is a highway=unclassified road, or whatever!
Finally on this line of throught, For events such as the silverstone
grandprix, there are marked grass tracks, that have no indentation, but a
marked out and used by traffic, but are just grass. These go around the
carparking fields. If a track is just sand over a desert and is nothing
more than sand, if traffic semi freqently passes down a similar line, then
it would seem ok to call it a track of somesort. In this case the track is
there because of humans memory, rather than a scar in the land, but none the
less its a track.
That's all I'm gunna say on tracktypes I think. Please check back over the
fasinating debate sometime in mid decemeber, when all this was covered.
After using this tag in all 4 seasons I have come to the opion that I have
stated above. Its been tested!
