For the access tags (and we do discuss access tags here), it is common
practice to have country-specific defaults on certain highway types as
listed in the wiki [1] and only tag what contradicts those defaults.
I'm not sure any of the current routers uses these country specific
defaults. My guess is that "normal" roads will always be allowed for
everybody except specified explicitly differently, and motorways and
roads
with motorroad=yes will exclude certain slow vehicles. Cycleways will
allow
cycling and footways walking and usually not cycling. If some country
specific defaults are different and nothing is tagged, it probably won't
work. Usually mappers do add "default" properties explicitly on roads
and
ways, and the more mature a region is mapped, the more of those
attributes
you'd usually find.

I think many mappers are very happy with these country specific access
rules. This will prevent an overload of tags on roads. There is only one
router I know personnaly and that is the creator of the Openfietsmap
<http://www.openfietsmap.nl/home>Garmin map. His map (lite version) is
also worldwide
<http://garmin.openstreetmap.nl/>available.
He uses this country specific scheme.
Part of his script is here. I think it makes clear that trunk roads are
not
accessabel for bicycles in some countries regardless of any "bicycle=no"
tag.
highway=trunk & mkgmap:country ~
'(NLD|BEL|LUX|FRA|DEU|AUT|CHE|
DNK|HUN|ROU)' { set highway=motorway }
highway=trunk & bicycle=no { set highway=motorway }
highway=trunk { set highway=primary }
In Germany trunk generally is able to cycle.
In Germany we tag "car-roads"/"fast-roads" with motorroad=yes, this could
be trunk and primary (and perhaps secondary too?). This roads are
forbidden (implicit) for bicycles and foot.
Think the added 2 (and changed 4th) lines are better:
motorroad=yes & mkgmap:country ~
'(DEU)' { set highway=motorway } //think for CH and AT the same
highway=trunk & mkgmap:country ~
'(NLD|BEL|LUX|FRA|AUT|CHE|
DNK|HUN|ROU)' { set highway=motorway }
highway=trunk & bicycle=no { set highway=motorway }
highway=trunk { set highway=primary }
