The problem of getting a person across a state from border to border in a day’s comfortable travel is not by speeding up a train or highway speed limit. For California (and Texas, perhaps) it would be by subdividing the state into three or four smaller state-sized manageable governed areas. As it was for the Carolinas, Virginia, and the Dakotas in other years, to wit. Mot joking.
If you want to go from S.F. to L.A. or San Diego in a hurry, the solution is to buy a freakin’ plane ticket on Southwest. No one except the politicians and the folks getting rich on this boondoggle (and there’s probably an overlap between those two groups!) wants this stupid train.
You may be “ mot joking”, but are you serious?!?!
Sentient beings don’t care about how many state borders they cross in a day.
Which, I guess raises the question: Do you?
