Or, you know, you could drive (or bike! or waymo!) to the local train station, which should have <30 min, well-scheduled, predictable headways to major cities, then take a train that goes 150+mph, and then drive (or bike! or waymo!) to your final destination, for _far_ less total energy expenditure.

Every car in a train-caravan is schlepping along its own engine, crumple zones, airbags....and with rubber tires...

...its frankly idiotic.
