It depends on how you look at it. With a more contained and 'gathered' approach, I would think that it would foster a tighter 'community feel' between the neighbors than in a more spread out model. That doesn't seem devoid of human interaction to me.
Each house has tall hedges surrounding it, acting as barriers from neighbors. It seems you'd have to walk all the way around if you wanted to visit. Then, everyone parks in the circle so the car you drive is the most prominent feature of your home.
It looks cool, but I can see how someone might consider it odd.
But all properties are connected at a central point, making it easy to put together gatherings of everyone in the community (e.g. 'block parties'). As opposed to a similar number of houses in a grid pattern. That's just my impression though.
