"Evacuated underground tunnels for low drag long distance high speed trips."
That's interesting because while I've heard of and thought about the concept of a vacuum tube train that could go ridiculously fast, I didn't think of a merely low-pressure tunnel that ordinary cars (with pressurized compartments, anyway) could use in flexible manner. You wouldn't go 15,000 mph, but you could do several hundred pretty easily.
Think 100% electric high speed trains that let cars 'board' at highway speeds. Evacuated underground tunnels for low drag long distance high speed trips. Hybrid Maglev cars that rocket down the highway on a cushion of air while being inductively charged. Even things as simple as highways without road signs of any kind.
