[Tagging] highway=track access

[Richard Fairhurst]

Hi all,

There are almost 8m highway=track objects in the database (thanks 
taginfo!), third only to =residential and =service (thanks TIGER!).

I'm interested to know what level of access people believe this implies 
in their home countries.

Here in the UK, for example, highway=track is often used for private 
farm tracks, so you can't safely route over it unless access tags have 
been added. But evidently that's not always the case elsewhere.

http://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access-Restrictions 
has suggestions for a few countries, but is missing some pretty major 
ones, such as the US and the Netherlands.

cheers
Richard
