If we assume the player walk straight ahead ...

... how far can he walk before the physics mess up in a walking sim?

The reason I'm asking is that I'm playing with the idea of creating a VR experience based on Wealth Shown to Scale.

I'm aiming at a very long corridor with wealth shown with grids of 1x1 cm² rectangles each representing 1000 dollars. In order to show Jeff Bezos 185 billions, if I go for a height of 5 meter (equals 500 centimeter = $500000) the length will still need to be 368 kilometers. (And that is just him, not the 400 riches people in America.)

Of course, people walk 5 kilometer per hour, so it is unlikely that any player will walk 358 kilometers in VR. But I like to have some idea of what is possible.

Of course, I can start out in a negative position, so that it moves toward 0,0,0 and then past that. Should give a bit more distance before the physics gets messy.

I noticed that a floor scale of only 500 meters caused my VR avatar to jitter vertically. So I need to find a way around that.
