You get 700 mpg only if all the passengers can be magically teleported from their homes/businesses to the rail depot.

Add up all the cars and buses driving to the station and back again - the mileage takes a big hit.

If we are only considering PMPG and not worried about route flexibility, capital construction costs or commute time to the terminal I suggest we all travel by Space Shuttle. Sure it burns 700 tons of fuel in the first six minutes of flight, but after that it doesn't burn any additional fuel for two week mission while traveling 18,000 mph. That's more than 6 million miles on a tank of gas. And the fuel is mostly eco friendly hydrogen and oxygen. Sure you have to drive to Florida, it only departs three times a year, only carries seven people and doesn't go where you want to go. But hey it is high speed, government built, and looks cool. /sarc
