I noticed some distance differences between open source car and the graphhopper maps car profile. I have used the germany pbf and the ch preparation before calculating the routes.
Did I miss some optimization I can activate to get closer to your routes or can you give me some hints, where the open source version is different to your production version on graphhopper maps.
Can you also give me some hints how you achieved that the truck drive on the highway instead of national roads? I tinkered around with the weighting and tried to prioritize highways, but I’m not that satisfied with my results.
