I like the idea more than the reality. If we get a bullet rain from LA to SF, it still leaves most of the urban and suburban population in both places stuck at home, with an antiquated and unworking transportation system. I'm in Oakland. If the thing goes to SF, I have to get there. That's a bus or Uber to BART, BART to SF, and then Uber or a bus to the train station. When I get to LA, it's the same thing. End result? 2-3 hours of secondary transport, and 2 hours of primary transport. 4-5 hours total. lol
Same thing can be said about getting to airport, then also adding time to get a special touch by TSA.
