That may be the case where you live but I wouldn't make that assumption 
worldwide.  I certainly wouldn't assume that a track in England without 
any access or designation tags was publically accessible.

Routers have a difficult job to do of balancing physical and legal 
restrictions - there isn't a "one size fits all" answer.  It's more of a 
problem for OSM because commercial datasets for car satnavs tend not to 
include the wealth of paths and tracks in OSM in well-mapped areas.
