I'd like to see those communities surviving to the same standards of living without having motor vehicles around them either. You want to build walls out of concrete ? Or wood even ? Well, have fun transporting all that in a cart.
Those communities have phones. Manufactured goods. They're watching Game of Thrones. If you remove motor vehicles all of that simply isn't possible due to the loss of productivity.
While I agree that preventing the intrusion of motor vehicle in residential areas would be good (ie have main roads where they're allowed, and small residential streets where they aren't. Lots of cities in Europe shifting to this currently), saying that the negatives outweigh the positives "in a lot of cases" I think is completely incorrect.
