Looking at random houses in the USA, I see many bizarre neighbourhoods. This street view photo shows a bunch of houses which are clearly separated from the front lawns, to the point where they look like "anyone's land" patches of grass. Absolutely nothing prevents or hints at anyone that they should not be playing, chilling or doing whatever on those squares of grass in front of the house. And from the looks of it, considering the condition of the grass, a lot of people have indeed walked, ran or even driven around there with cars.
Who would want such a front yard with zero privacy? Are you supposed to take out a grill and stand there in the open and grill your meat? Is it even part of the property, or does it belong to the city? If so, why is the road so far away from the houses, or the houses so far away from the road? What's with that little "buffer zone" which apparently is neither "a place for anyone" nor their private front yard?
