Duration of a ferry varies greatly

[OlafFlebbeBosch]

I am tripping over ferry links without durations in OSM, like: Way: ‪Autofähre Mondorf-Graurheindorf‬ (‪9651935‬) | OpenStreetMap

Planning to use the ferry by car takes 11min, while taking the ferry by foot it takes 23min, which is pretty slow since the distance is only 400m .

This should be fixed by the upcoming v8.0 release.

Indeed ! Thanks! Just built current master and imported the data and routed a car and foot.
Both have now the same duration.
