Unfortunately, US civil engineering is very dogmatic, so if it isn’t approved by AASHTO it won’t be done.
The civil engineers also like absurdly wide turn radii to accommodate 53 feet trailers and large fire trucks even in residential streets, so you end up with comically wide roads even for dead end suburban streets. https://thumbs.dreamstime.com/b/suburban-street-2779407.jpg https://thumbs.dreamstime.com/b/suburban-street-2779407.jpg
