I have observed strange wheelchair routing. Please see Freemap Slovakia, digital map.
You can find the configuration at https://github.com/FreemapSlovakia/graphhopper/blob/master/config-freemap.yml. OSM data is never more than 1 day and 4 hours old.
Also wheelchair routing returns always 400 for wheelchair and fastest weighting (therefore I disabled it in the config).
Is there anything I could do with that?
