Has it occurred to you that not everybody has perfect health all the time?

Then those people can avoid riding the hyperloop?

Luckily we didn't use the same BS excuses to stop building planes...

You can't actually expect that you wouldn't get sick the first minute after you enter the tube.

What? That's what 100% of the population expects when entering any vehicle. "Getting sick the minute they enter" is neither a common expectation nor a common occurence.

Then imagine yourself having to remain there next 29 minutes and die!

Well, that escalated quickly.
