Itachi considered the question, even as he experimentally rolled the ball beneath his foot, getting a feel for the technique. He didn't have a good perception of how distance was covered in those machines, given the speed they moved and the way the sensation of movement was displaced.

I have also heard that those who go outside the Institute's walls at night still find themselves back in their beds come morning."
