Using Directions Post (json or geojson) or with just two points with these coordinates the routing goes into highway directly taking a longer route;
[[0.069354, 43.234675], [1.233384, 43.59861]]
But using Graphhopper (or PTV API) with heavy vehicle profile it takes the desired routing;
Note the recommended route for ORS is the longest (both distance and time). Knowing this particular route, I believe a heavy vehicle will never the ORS recommended route.
It seems ORS favors highways for heavy vehicle, sadly highways go with tolls in many countries.
Thus my question: why ORS is suggesting the longest and most inappropriate route for a heavy vehicule as recommended?
