>Now, why I'm not fond of highwaytype :

It was just a default.  I'm not suggesting it, I'm suggesting thinking of 
something else.   Just ignore it, and suggest better.

>It's self-explanatory

Well it is for roads that have lanes, but I'm talking about tagging roads 
that specifically have a lack of lanes, and are just a strip of tarmack with 
varying widths.  So in that sence its unfitting, and not very 
self-explanatory

>k="carwidth"

This would be fine, if there is a few standardised tags, as well as having 
the freedom to add additonal ones if a person wants.  I think there is only 
really a need for the 4 types I previously >stated, as other types would not 
make jounrey times any different.

The problem with carwidth, is that the 3rd and 4th type of road I spoke of 
are the same width of tarmack, but have less width when the grass in 
included, so passing is very much harder.

>Example :
>k = ???? (don't know the English word for "drive past each other")
>v = normal(default) | caution(?) | difficult | impossible

k=Passing?/Passability?

That is quite a good suggestion.  My only concern is if a person did want to 
add additional road widths as x meters/feet.  I personally think thats 
unnessesery, but someone may want to.  But yeah, this seems like a good 
proposal.

If there is some agreement with this then I'll propose this.

I had similar ideas when tackaling the tiny roads in pembrokshire.  The 
Governement fitting electronic systems sounds like a very expensive way to 
go.  Just widening the road would be cheaper.  Most councils in more 
developed areas such as norfolk just go nuts on signposting all the passing 
places.  This is completly pointless cause usually if you can see the sign, 
you can already see the passing place!   I usually find the biggest concern 
is getting stuck behind something like a horse, or many horses.  This is 
inposible to map, except if a road is frequently used by horseriders, and on 
average the road is a poor choice to take.
