Yes, that was my first thought as well.
But the Google Maps screenshot says 0.2 mile which means that it’s just exactly one time around in the roundabout and not insanely often, so that’s not the case here.
I looked up the roundabout to see if there’s any reason why you’d need so long (e.g. it’s not really for driving and you could be 1mph/kmh or so, but it looks like you can drive normally on it.
