Musk gave a presentation on Tesla Semis and competing with Rail. And if you take like 5 semis and put them butt to butt (to reduce drag), autonomously, you can beat the cost of Rail. And you essentially just took Rail and expanded the reach of it with all the highways in the US. So that is the grand plan, to go after Rail.
Presumably the congestion added by a bunch of 250' long trailer centipedes on the road would drive commuter traffic into Musk's surely-by-then existent hyperloop?
