it's not but it's not happening in america. not sure what the left wants, you can't demo cities like los angeles and rebuild for obvious reasons like people still have their businesses/houses there, but even if you could it would be a decades long project. all this infrastructure should have been built 100 years ago. if you build it now you won't be around to benefit from it. also america has a crime problem so no one wants to use public transportation. this whole conversation is a waste of time, go build a time machine and go back 100 years and convince people to build your walkable cities.
