You would also probably need a vehicle with a tight turning circle, and
a quiet road - so agree it would be an unusual choice. Agree false
positives.
But the points about machine routing make me think maybe I shouldn't
be closing these off? Any thoughts?
Your example looks like a very common roundabout flare 3-way node with a
cycleway crossing node. Taking the JOSM code as an example, perhaps the
"ImproveOSM" validation also has a segment length test (<20m?) so the
crossing is suggesting a more complex junction?
Eg, at node https://www.openstreetmap.org/node/26187838
Personally, adding restrictions to this common a use-case should be
unnecessary (fix once in the router, not every roundabout on the map).
Save your effort for more complex junctions where software
understandably needs a helping hand with real-world oddities.
Happy Mapping,
James
