I understand that this is mainly a discussion about density, but the US is super diverse in its population densities. I was just curious because I happen to live in a very rural area, but if you travel 30 minutes you would be in the most densely populated area of my state. Correct me if I'm wrong, but most of these increased fees would be implemented at the state level and could seriously impact those that live close to dense population centers, but have no available transportation other than cars.
What viable alternatives are there to cars in large countries like the United States, where it is not feasible to create the infrastructure for public transportation?
