> We repeatedly make a political decision in the US not to prioritize them
Public transit can be fast and efficient if it is prioritized. That may require raising the federal tax on gasoline (last raised thirty years ago!!!) and directing that overdue increase to funding alternative transportation options.
For the higher density cities, cost is a major factor. I remember seeing a study or article comparing cost and time to build a subway in the US vs a European country. If I remember correctly, it tooks years longer and cost tens of millions more for a similar route even adjusted for local cost differences.
I would like additonal funding for many things. I would first like to explore efficient use of the money we do have in order to make it all more effective.
