7.2 g acceleration. You could strap a human on there and they'd survive the acceleration phase.
For an untrained person this might well be lethal.
Yeah this link says most people can only take 4 to 6 g, but fighter pilots can take up to 9.

Only 2 seconds of horizontal g? Not unless they weren't securely against the seat and died due to blunt force trauma from being slammed into the seat back.
That's an expensive way to look inside your own skull.
Now we just need those inertial dampeners!
What a way to spill your cocktail...
Your move hyperloop.
So what’s the limit of the human body? That’s more than a couple g.
I don't know but it seems like the simple answer is to just not accelerate that fast. I doubt this was an attempt to imply that we should do this regularly. It's just a test to show what the technology is capable of. There's no real benefit to accelerating to that speed that quickly vs doing it over 30 seconds or longer.
How far did it travel in that 2 seconds?
If acceleration were constant (and my math is right), it would be 194m. We can assume due to air resistance being proportional to the square of the speed that acceleration will be more initially and less later, so realistically it will be >194m
