Yeah it’s not that we don’t want to use the train, it’s that the train has been successfully turned into an objectively worse option in every way thanks to decades of lobbying and underfunding. If there even is a reasonable train route between your destinations, it would likely take 2-4x as long as driving, be 4-10x more expensive than the gas for the drive, and would be an uncomfortable and unpleasant experience that would still require a pickup and decently long drive (or further use of the barely functional public transit system) to get to the final destination.

If you’re not a shipping container, there basically is no public transit infrastructure in the US. It only exists in cities that have chosen to make significant investments in it, and even then in most places it’s like one arterial light rail and then some busses with crappy coverage. For anything between cities or states, it’s nearly the same price as flying to get a charter bus or train ticket.

The only thing that would solve this problem is extremely aggressive and unpopular legislation, or some benevolent trillionaire to actually do a hyperloop type project without immediately coopting it into just a shittier highway. Market forces and city governments will never create real interstate transit networks. Less aggressive legislation making it more expensive to keep and especially buy/make new cars would help, but it’s political suicide to say “I’m going to tax the good that almost every voter, and especially the ones with money and influence, have and use every day”.
