Going fast contorts our mental perception of the dimensions around us. The speed creates a more and more focused tunnel view. Horizontal(left and right) dimensions. Become more and more compact and less depthtually explored. The slower we travel, the more broad our sense of a scene is. A street corner to someone who constantly drives through it is really just a more linear array of the landscape, but to walk through it, and live through it, your frame of reference exponentially increases. This may or may not involve the signal of earths natural magnetic field in some fashion.
