Atlanta is rapidly consuming Barrow County, so I think I can comment as someone in Atlanta. It's much easier and far more practical to get people to change the kind of car they drive than to change what moves them.
I like to be able to take a peaceful ride along the highways that run through Barrow and go right up to any place along the way, then go back at will.
Cars have come a long way, and their impact on the environment will be just about none by the time we could get a ring of walkable suburbs built just outside the perimeter. The problems seem to be going away. Dense cities are potentially more efficient, but Georgia is a nest of roads and sparse population and still manages to be clean and productive. Forcing everyone into a skyscraper is probably overoptimizing.
