If you don't get it, go to an airport and run against one of those moving walkways. Let's say it's moving at 3mph. I can bet you any amount of money that I can run on that conveyor (in the opposite direction) such that if you shoot a radar gun at me it will say 3mph. I might have to move my legs twice as fast, but that's beside the point.
you moron, what your not getting is that it's not static.
it will speed up as you speed up, get on a tredmil and start walkign and have somone increase the speed as you speed up, see how far you get
