Yeah, even if you force it to strongly prefer the national bike network it won’t use it.
The problem is likely that we currently try to slow down on highway=bridleway: graphhopper/core/src/main/java/com/graphhopper/routing/util/parsers/BikeCommonAverageSpeedParser.java at master · graphhopper/graphhopper · GitHub
without considering tagging like bicycle=yes|designated …
@ratrun do you think we should fix this (or consider country-specific rules for bridleway access)?
And why don’t we have the same problem for foot where we do not include bridleway in the allowed highway tags?
