Why not put in a maglev system you drive on and it takes you cross country for a few dollars, run it on renewables. Then with less traffic on highways you don’t need to have high dollar systems for people not to drive their cars so they can sleep or be on their phones. This system can charge your car, give you wifi and can let you stop to eat or pee. It also could be set up to move trailers by themselves to destination and driver would pick it up and deliver it, at huge cost savings. This is not the stupid tube by Musk but ground level mover. Speed would be in 250 to 300 kl range.
