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. Still - a track may be usable to reach a destination. For routers they may appear at the end or the start of a route e.g. access=destination any may not be used for through traffic.
