I can’t see anything wrong with these examples? If you switch to curvaturefastest the heading is used: https://kurv.gr/dHmh4 If the detour is too long/troublesome, the routing engine will choose a different direction. The detour is using a lot of cities, and cities are avoided.

[Bild] devemux86: So it seems that the heading direction has small priority in Kurviger routing. And is not reliable in navigation, where drivers expect it to work every time. It is not designed to force a direction. It is meant to favour a direction. In the example above I would rather tur…

[Bild] boldtrn: In the example above I would rather turn around instead of riding through the city. The curvy route is designed to be an enjoyable route. So the result is OK IMHO. Agreed, this makes sense when planning routes. However, while driving and requesting rerouting, users expect the…

It is possible to create a larger influence of the heading on the routing. However, I am not yet 100% convinced we should do that. This can lead to significant and potentially frustrating detours, often unintentional. Unfortunately, we currently don’t have the option to provide nice u-turn announc…
