The wiki also admits that tracks can be paved which is unnecesary for
agricultural and/or forestry uses only. We have to accept mixed uses
as well.
What is ofter ommited in this discussion is the tag
"tracktype=grade1..5" which was created almost at the same time as the
"highway=track". It is perhaps not perfect and the pictures used as
examples cannot be generalized, but it existed before surface and
smoothness tags which have their own defaults ("smoothness" may vary
on weather conditions and is subjective, "surface" may change often on
short distances, etc). A highway=track + tracktype=grade1 can be
safely used by normal cars.
Perhaps in Germany, all tracks have limited access. But they all have
traffic signs indicating the restriction(s). If the tag "access" is
missing, we cannot assume that the mapper forgot the restriction !
What is true in Germany can be wrong in many other countries. Excepted
if we admit that OSRM is a German centric routing engine.
Interesting in the wiki is the big difference between european
countries about the default access on tracks:

So, depending where you leave, the default behaviour on OSRM (or any
similar routing engine) might completly correct or wrong.
