Hmmm, this is getting really ugly.

Now we have:
highway=unclassified
highway=unsurfaced
highway=track
trackgrade=gradeX

BTW: Please don't use very specific terms, none english persons like me 
don't tend to know what "tarmac surface", "metalled surface" is. If you 
are not able to describe a feature in a way that most people do 
understand (including none english natives), please don't add stuff to 
the map features page.

Unless you are able to explain in the map features page what the exact 
differences of the above types are, I tend to simply remove this from 
the map features page. We already have enough stuff in that page that 
people don't understand how to use - and just adding a new thing is no 
real cure.

Don't explain anyhing about this new thing by mail, this will get buried 
in the mailing list archive pretty shortly.

P.S: Yes, I'm pretty upset by some people thinking they are better than 
others - so they know what to do and don't need to propose any features 
first.
