Are our cities designed the way they are because people are unfit for better forms of transit, or are people unfit for better forms of transit because of the way our cities designed?

Is your contention seriously that we're incapable of improving anything because design decisions that have been made in the past are now unchangeable? Nothing must ever change after it is built for the first time? It's impossible to nudge people towards better transit possibilities incrementally through more thoughtful design? What a ridiculous take.
