I found the road speed stuff in the source already. It seems it is in the default
style hardcoded by street type/classification which should be possible
to override with some tag i think.

And a maxspeed has nothing to do with what i hav a problem with. All the
roads i travel dont have a maxspeed set, are primary and thus for the 
time calculation my GPSMap 60 takes something like 80 km/h - which on 
la palma is on some parts more than twice the actual speed one can 
travel ... An its nothing time dependent - its something which depends
on the physics of the street - tight corners reduce the speed beeing 
traveled ...

Typical speed/ average speed would be more accurate ...
