A. The tip with search u-turn or “wenden” you thought up well. Makes locating easier.
In a tool version, of course, the presentation should be completely language independent.

B. Route planner design.
I do not think of automatic corrections actually. I prefer to keep control of this myself

C. The tip for automatic correction I doubt, since I prefer a ROBUST @ simple rule

The Rumbrummer proposal I had imagined as follows.

  1. Assign misplaced Shaping Point the coordinates of the enclosing turns then MAGIC ! Only the unannounced Shaping Point remains.

  2. But Shaping Point & U-turn(-98) are not necessarily enclosed between between 2 consecutive turns at exactly the same location.

     A. False turn > Shaping U-turn > Correction turn. U-turn CLEARLY enclosed. Robust.
 B. (Continue) > Shaping U-turn > Correction turn. U-turn not enclosed. Robust? 
 C. False turn > Shaping U-turn> (Continue). U-turn not enclosed. Robust?

D. Left or Right U-turns because of this are extremely rare. I’m not worried about that.

The essential not to forget.
Design accurately then hardly any such corrections are needed
