The most recent version of my code now pays attention to these OSM tags: access, bicycle, foot, hgv, motorcar, motorcycle, psv.

Unfortunately, the Garmin codes don't appear to know about motorcycles
(they lump motorcycles and cars together) or horses (or taxis, either).

So if a way is tagged with one of those, i.e. hgv="no", the gps will know
about it.

If this is not adequate, we can look into adding extra information in the
style file.

Cheers,

Mark
