Hi everyone,
I’m facing a routing issue when a destination is located in the opposite direction of travel, near a roundabout.
The Problem: Instead of routing me through the roundabout to perform a full U-turn and return back on the same road, GraphHopper suggests a detour by exiting the roundabout into a side street (left or right).
Basically, it seems to be avoiding a 180-degree turn via the roundabout, even when that is the most logical and shortest path.
Example details:

My Question: Is this behavior controlled by u_turn_costs? I am using the default configuration, and I would like to know how to encourage the algorithm to use the roundabout for U-turns instead of taking side-street detours.
Thanks!
