Traffic completely stopped on I-40 earlier today because of road work, and I had a view from a side street of this ridiculous line of 18-wheelers stretching seemingly forever. Hardly any normal cars, just trucks. Seemed especially inefficient as a freight train went by.

I believe there is a company formed by ex-Tesla engineers working on autonomous railroad cars. Perhaps we will see shipping containers on wheels zipping by on rails the way trucks do on the highways.
Correction: ex-SpaceX

@cliffordbeshers Looking at that now… Interesting. I can think of all sorts of challenges but I’m glad people are working on it.

As more semis become electric they won't be more efficient but at at least they’ll emit less carbon and micro-particulates.
