Right. But we're talking about large trucks, not a train. Unless
drafting, each truck has to deal with wind resistance. But, with
drafting, your point makes the argument that rails would make a
significant difference.
Maybe the US should be financing a new kind of rail system or modify the
existing one. One where each freight car is self powered and can exit
the tracks and use rubber tires for "the last mile."
Yes. As an engineer, it is pretty easy to imagine a vehicle with both
tires and steel wheels, that can easily transition from one to the other
"on the fly" while driving at speed. It's especially solve-able with
self-driving vehicles.
The challenge (as always) is that a good new solution is always crowded
out by a bad old solution that is already established. See quote below.
