Because your whole argument ignores reality. Any politician who makes some drastic change will get voted out and someone who will undo any made progress will be voted in.

Countries in Europe didn’t magically flick a switch and get good public transit. Their whole societies have been shaped since pre-world war 2 to where their populace is on board. Incremental change for 70 odd years was needed. They also didn’t have their whole train network get bought and destroyed in the 40s and 50s.

Your opinions are valid and stupid at the same time. Nobody is going to argue that public transit is bad, it’s just completely unfeasible in a lot of places without a lot of incremental change first. Nothing of this scale happens without buy in from the larger population.
