Actually a really good explanation of this (among many other ideas) can be found in The Elegant Universe by Brian Greene.
That’s ok. I just found a simple explanation in the AAA Driver’s Guide. Seems that when I drive toward New York, that’s what makes it appear to come closer to me, and when I drive away from it, that’s what makes it seem as if the “space is expanding” between me and New York.
