> blah blah .. Vestibular system .. blah blah Sorry, but the reason they don't work is much easier to describe using momentum. You can't stop on a dime, turn left quickly, or any "regular" human movement that alters your momentum, because you (~50-80kg) aren't moving*. Even if we HAD no Vestibular System, this would still not work as expected; we fall over the moment we try to "stop" while running at full pace.
