[Discussion] What are your opinions on this Not Just Bikes comments on "fixing" North America?

It seems he has given up on it and was asked for his opinion.

Imo you don't need to fix the US entirely, should be doable to fix small areas you want to live in. It's nice if an entire city is well designed, but the greatest inpact is in the area you are 95% of your time in anyway, which is much smaller.
