You're missing many issues that won't be fixed by more money: 1. Much of the world is low-density. (and we like it that way) Public transportation would be running empty nearly always. Anything less, and service times become awful. 2. We've learned that public transportation isn't OK in a world with viruses. 3. People keep personal stuff in cars. 4. Lots of people don't feel safe on public transportation. 5. Even "good" public transportation isn't normally door-to-door. People will need to walk much more. That could mean getting sweat-drenched and smelly in hot humid weather, getting frostbite in cold weather, struggling with disability, or trying to keep kids from straying or straggling. 6. Public transportation is dirty. The germs aren't from family. Everything is gross and nasty.
