LA to SF in 6 minutes? Meet Elon Musk's 4,000 mph transportation concept, the "Hyperloop"

61. How do make it through the day so worried about things for which you are not responsible?

No one implied it would be easy, and they have only released the barest minimum of details. Why worry about stuff they obviously will have to plan for?

Gimbaled seats will allow canceling out turns as well. You are quite correct that it will have to be fairly straight, but not as much due to human limits as you seem to think. As I pointed out, you could get 1.5 G acceleration down the track with no apparent motion at all. I really don't know why you think it would stress a person any more than sitting motionless in a stationary recliner.

Catch fire? In a vacuum? In a car with essentialy no moving parts? Medical Emergency? 6 minutes to the station, why would you stop? What do maintenance/emergency personnel breath? Um, air, obviously. Either in pressurized suits or the repressurized tunnel. How fast can personnel get to a disabled air craft? You need the vacuum to hit 4000mph, but repressurize and you still have a maglev system that could easily do 60 mph without breaking a sweat. Maglev disabled? The cars will undoubtedly have wheels they will ground on when not levitated. Earth's radius will have to be accounted for in the design, but it will have nothing to do with human comfort. Do you really think they would not designed the tube for repeated rapid depressure/pressure cycles?

Nothing will be able to counteract a catastrophic tube failure at the point of failure, obviously. Worst case scenario, if an earthquake severed the tube, game over if you get there a second later. If you are more than a couple seconds away, you will be running into a steadily increasing air brake. There's no way to make it perfectly safe, but I'd rather be in the tube that fails to being pressurized than in a plane that fails to being depressurized and then falling for 30,000 feet.
