 I worry about this a lot. I think the size of the circle is dictated by who else you can expect to be in that circle with them. With the automobile it could be anyone.

Cul-de-sacs suck but are desirable because they remove a variable. I want to put roads under ground so kids can have the run of the neighborhood again. 
 It can also be expanded by who you expect to be in the circle.  If kids are meeting up with friends at a park a mile away, and you know a few of the neighbors in between, that's going to be a quite safe radius. 
 Yes. My kids have a very small radius because My wife and I are introverts. In nearly 8 years of living in this town we have made 0 close friends. We don't know the people in the next house much less whoever lives by the park.

In my defense all the neighbors that I did know recently moved away. But they were all retired. We accidentally moved to a neighborhood with nearly no kids.
