Absurd detours on the highway maps HERE

[Hubert Thoring]

As some have already mentioned, 27 waypoints for approximately 5500 km is very few to have a clear route. As Rob already wrote, it's better to plan day trips.

Avoidance routes should also be used as long as it makes sense.

Yes, thank you! I didn't know that OSM didn't support long distances...
