... all mechanical forms of transportation except for human powered vehicles and emergency response vehicles, are limited to 35 mph.
That's a different sort of vehicle than the current automobile "standard" but fine for your semi-rural purposes.
It also means you take a train or ship on long trips, still 35 mph, but you're not driving, so you get to look out the windows, walk around, meet new people, watch movies, and generally have a relaxing trip while getting to know the true size of the earth on a human scale.
Of course I can't force anyone to live in my utopia, but I do think we could provide everyone with safe, comfortable, low energy housing, creating communities where cars are unnecessary, and even considered undesirable by most people.
In "developed" nations these communities could be created by the modification of existing infrastructure, rather than typical high energy tear down and rebuild construction.
I also think for the most basic guaranteed forms of housing that people ought to be able to "own" their home in some sense, secure in the knowledge they can't be evicted unless they become a terrible nuisance or danger to themselves or others; that they can paint the walls inside and out any color they want, install whatever flooring they like, and generally modify their living space in any way that's not harmful to the neighbors and structural integrity of the building.
Our U.S.A. society discourages the formation of true communities in many ways. We are isolated in our automobiles, we are isolated and insecure in the place we inhabit.
I think that makes it easier for the oligarchy to manipulate us, to sell us the "consumer" lifestyle, to keep us in a corrosive fog of lies, insecurity, fear, and passivity.
