Hi Martin,

Some of the highway tag values are not clear. For example, scout does
not route over highway=tracks, unless you are in pedestrian mode. It
seems like a reasonable decision, perhaps all of the routers do this,
but the wiki documentation says nothing of the sort, and it surprised
me. If I see some weird route, related to missing highway=track tag,
should I change the osm data, file a bug into scout, edit the
highway=track wiki? I have no idea.

A start would be to have the 3 or 4 popular routers document what they
are doing with the tags, since the code is proprietary, and then it
will be easier to sort out who to blame when a bad route is generated.
