And speed is relative to point of view. If you look at an airplane from the ground it moves pretty fast but for the people on board their reference is the plane itself and they’re pretty much stationary. And, similarily to airplane, when craft speed or direction changes the force required affects to people on board too and that’s where limits of the human body come up pretty quickly.
