The Netherlands is a similar shape to the continental contiguous United States yet we have an excellent public transport system. Very good trains and every population has awesome cycling infrastructure.
The US could have all of this and more in their populated areas. They're the richest country in the world. Why is the infrastructure so neglected? It's clearly a choice.
US army can deploy air force, tankers, soldiers and all the logistics together with Burger King anywhere in the world within days and somehow people that pay for it still think a simple rail in their home turf is impossible.
Isn't Netherlands trying to deter from car use by laws and taxes and at the same time funneling public money into railroads and bike infrastructure?
>The US could have all of this and more in their populated areas.
Probably people in US have other priorities and that means there are other public policies.
The question to ask is "who owns the rail lines?". That matters for having a good rail system. It's basically the same problem for why the US doesn't have fiber internet available everywhere, too.
