This is something you probably have to ask them.

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.

Mapfactor Navigator for Android is capable of exactly doing this - why
arent the others?

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.


Cheers,

Andy

I live on a track and no routing routes through them except Mapfactor
Navigator (Android)

ANY road should be used for routing - track/service do have an implicit 
access=destination and should not used for "through" traffic but have
no route restrictions otherwise.

I have complained many times but i stopped ... You cant route to my home
but i am not going to retag the roads just for this purpose.
