I think the joke is people keep posting the "you can drive x hours and still be in y location", but really, you can drive indefinitely in one neighborhood, without every leaving. You could stay in the roundabout for as long as you want, just like you can drive from South Africa to Finland, or whatever.
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.
