[GraphHopper] has anyone customized an existing vehicle?

[Peter]

Hi Andrew,

yes, that customization is possible, although not in an externalizable
'script'. It is currently done directly in Java, although we have plans
to introduce some scripting at a later time. Have a look into the
FlagEncoders:
https://github.com/graphhopper/graphhopper/tree/master/core/src/main/java/com/graphhopper/routing/util

e.g. for bike the common super class 'BikeCommonFlagEncoder.java
<https://github.com/graphhopper/graphhopper/blob/master/core/src/main/java/com/graphhopper/routing/util/BikeCommonFlagEncoder.java>'
is used where different profiles like racing bike and mountain bike
extends and change behaviour.

Well, not really obscure, the track is marked with bicycle=yes and as
the road is highway=primary road graphhopper is trying to avoid that.
What we could do is also trying to avoid sac_scale=hiking or
surface=gravel (maybe the latter is already done).

Regards,
Peter
