This works in Japan and Europe because of geography. I'm not a smart man but I can tell you right now with 99.8% certainty that this has no chance of working. Look at it this way...Any city pair within 3 hours...it'll be faster/cheaper just to drive yourself. Any city pair +5 hours...it'll be faster/not much more expensive to fly. Our population centers are too scattered to make this efficient/time saving.
