railroad is better
The idea could evolve, though I believe they're on the right track. (ha ha) No urban runoff as with blacktop roads, the earth gets to breathe, and a polished metal wheel on a polished metal rail - you can't get much lower in rolling resistance than that! Imagine our vehicles, a car for instance. An 8" x 8" part of the rubber tire is affixed onto the road. Now multiply that by four and you have an idea of the rolling resistance that must be overcome before the car even starts to move!
What Buckminster Fuller said still holds true today, that the auto does not work without the infrastructure of toxic tires and smothering asphalt.
Also, to be nomadic is a type of freedom and security, knowing that if the '**** hit the fan', just pack it all up and roll on down the RAIL to a new and hopefully better location.
