Secret city designs that prohibit desired social behavior

[B' Spokes: Did you hear about the kindergarten teacher that became a bike/ped planer? Single file sidewalks, single file bike lanes, single file bike trails and no talking! And it goes beyond that, place designs get approved with conceptual drawings showing lots of people then when they build it lots of no loitering signs and things mentioned in the following article so the place ends up looking sterile and void of life... and we call that nice pleasant design? What's next to the road is as important as the road its self, we need to put an end to false idea that accommodating people is a bad thing.]
