That is a perfect example of something that isn't a turning circle. The
tree in a bed prevents you using the full width of the circle to turn
in. Were you to map that as highway=turning_circle width=10m (say), a
7.5m truck, which would be able to turn in a 10m unobstructed turning
circle (eventually), would get stuck trying to make it around that loop.
