Please add "per direction on a road". Still waiting for a good way to tag
maxspeed per direction. What we call a "Geschwindkeitstrichter" in German -
the continues limiting of the maxspeed to a lower value e.g. 100/70/50 up to
a crossing. This is typically not reflected driving from the crossing where
only a maxspeed end sign basically is put up.

I also see ofter a limit in the inner lane in a corner but not on
the outer lane ... This can currently not really be modelled.

Probably a maxspeed:forward=50 + maxspeed:reverse=100
or something - How does this combine with wet and probably even
vehicle based limits ... maxspeed:forward:motorcycle=50

maxspeed:wet:forward:motorcycle=50

Afterwards add time based maxspeeds :)

I think we'd need a generic way to tag conditional ...
