I dunno, I grew up in the suburbs and ufmace summed it up pretty well. My neighborhood wasn't explicitly gated, but the meandering streets with a million dead-ends may as well have been a wrought iron gate.
It's pretty obvious to everyone that the nonsensical street layout was designed to keep everyone but residents out.
Every house had huge lawns, and because the houses were all built as part of the same subdivision development, they were all roughly the same age. This created a lot of keeping up with the Joneses, where one neighbor getting a new roof meant a cascade of people getting new roofs. One house got a paint job and suddenly the whole damn fuckin' street is painting houses.
Getting anywhere without a car is nigh impossible. The neighborhood, despite being upscale, lacked sidewalks (I guess they never thought anyone would need 'em, the residents ain't poor after all), and once you leave the neighborhood you face a 5-lane arterial where the unofficial speed limit is 50mph and drivers have no conception of pedestrians. The sidewalks are wide enough for one person - if you're unlucky enough to meet someone coming the other direction you get to do a silly dance around each other so nobody has to step into 50mph traffic.
Crossing this street is also nigh impossible until well after I moved out of that place. There are pedestrian crosswalks painted in, but good luck getting any of the drivers to stop for you. Thankfully as of a few years ago they installed a real honest to God traffic signal. Small victories.
Anyways, long rant, but ufmace's "nightmare" suburb does exist. I grew up in one.
