In the plane people can stand up, help the one being sick ("is there a doctor on the plane? please come to the seat 34E" -- the steward is already there etc) bring him water, take him to the toilet. It's a big space. Nothing like that here -- everybody is trapped in the tube not able to leave the chair.

Imagine even worse case: fire in the pod. People burn having to remain unmovable in the seats. Again imagine the public response. Just an impression of having absolutely no chance to do anything at all is enough to scare most normal people forever.

It just has to be big enough for people to normally move inside. Everything else is good for SciFi but not for real use.

If you don't travel, then imagine your computer being connected to the control of the tube in which you are and where you can't move. Now imagine that you can't kill the program for a half an hour which is effectively killing you. Even if the chances are low for the killing process to activate, would you even want to try such an experience?

Instead of just crapping all over something that is in very, very early stages of merely ideation, maybe we could switch to positive intent and try to come up with some comparables? Having just returned from Disneyland, I nominate the Finding Nemo submarines which offer a nearly identical experience for 15-20 minutes (and are pitched as "fun" no less).

Now compare it to a car.
