I don't see the point of that example. It's a place in the countryside,
so people going there is probably aware they may need to travel over a
track. Anyway, there's a paved road that leads you only 220 m away from
Las Lomas, so you'll probably be able to reach the place even if unpaved
roads are disabled in the GPS. I'm sorry, but I don't see the need to
mark unpaved ways as paved.

Ok. But that will mean that in a generic map, a lot of places will be
unroutable if the GPS is avoiding all unpaved roads. To reach them,
the user will need to allow unpaved roads in the route. This will mean
routing through sand roads and gravel roads alike.
It would be great if the GPS could handle semi-paved roads, as was
mentioned, but it can't.
In a generic map, what will be most important? To reach the
destination, or to avoid getting dirt in the car?
In Cadiz, Finca Las Lomas, s/n, 11179 Vejer de la Frontera, Cádiz,
Spain, would be mostly unreachable if avoiding gravel roads.

There are lots of places like this.
A side-thought: paved roads aren’t always the best option for a given
region. They are more expensive to build and when they degrade, they
get “hard holes”(*) and fixing them up will usually create bumps in
every hole. If the traffic is low, gravel roads will probably be a
better option and better yet if rain is uncommon, as is the case in
southern Europe.

(*) by “hard holes”, I mean pot-holes where the edges are very steep
and the wheels will crash into it. Gravel roads tend to create
pot-holes with soft edges, a lot easier to drive over.

I don't agree with you. I think default style is a generic style, and
as such, it shouldn't do much guess but use the strict meaning of
tags. Gravel, fine_gravel, ice, etc. are strictly unpaved and I would
mark them as such in default style. More specific uses (mtb/race
bicycle/4wd...) require specific maps and thus specific styles.
@Mark: I'm also cyclist and for mtb use your "raining" point of view
of paved/unpaved is important to be considered.

Hi! In Portugal, Spain and surely a little all around, unpaved
gravel roads are common, even on urban neighbourhoods.
These are quite drivable and they will often be the only way to get
to some places. They are also suitable to all vehicles, even if they
will get covered in dirt.
There are also a lot of paths going through sand (forest roads) and
these will unsuitable to most vehicles (even a lot of 4x4s),
regardless of their width.
I find that while driving, the real issue will be the road
conditions and width. Will the unpaved road be wide enough for a car
or light truck? Will it have deep tracks due to soil erosion? Will
the surface be solid enough to drive in a regular car?
So, in real world GPS usage, I would like unpaved to mean “narrow,
earth roads”, while paved would mean any road suitable to all
regular vehicles.
Example: due to wind farms being built in a lot of hill ranges,
large, unpaved roads were built. These are gravel, wide roads, and
often are a better option to the paved, sinuous mountain roads that
go around every nook and cranny in the valleys.
So, I think that fine_gravel, salt and ice should still be “paved”.
Nuno Pedrosa.
PS: Sorry to “butt in” the talk. I’m usually silent in this list,
though I read most of the discussions. Your work is amazing and I
find that I can add little to what is being discussed, so I try to
keep my “noise” to a minimum!

I'd call that semi-paved but Garmin doesn't have such category
unfortunately. Since the default style main focus is on motor
vehicles I'd suggest to add surfaces like fine_gravel, salt, ice to
the unpaved list. And please add soil to it, it seems a quite
popular tag.

This "raining" part is probably what paved/unpaved is about: The
surface of a paved road should not change when it's raining
and your vehicle will not be covered with dirt when traveling on a
paved road while it is raining (at least not from dirt which was
part of the surface).
Do you agree on that (last sentence)?
Gerd
