My prior community did this... 50 to 60 years ago. I happened to meet one of the long-retired city council members who was part of that planning, and they chose the street layout -- a modified grid -- deliberately to prevent traffic / cars racing down the sidestreets. A few strategically placed walkways let people move between sections in pretty much a a straight line. It keeps kids off of the main thoroughfares, and it makes walking downtown (these days, more often a commuter heading to the train station, but also trips to the library, theatre, and restaurants) a very pleasant experience. It's also a community where kids can still walk to school (though it's wealthy enough that many nonetheless get rides -- lazy little buggers ;-). (It's also nice to not be incessantly driving over the uncomfortable alternative that is speed bumps. An annoyance in the nearby city, these days.)
