OK, I must admit that some maps can be somewhat dubious. Or, is it all maps?
Despite their shaky foundations some maps form the basis for many centuries of human (mis-)understanding, only to be subsequently overturned by a new (and improved) chart. For instance, the geocentric models of our cosmos courtesy of Aristotle and Ptolemy were not replaced for around 1,400 years, until Nicolaus Copernicus proposed a heliocentric view of the solar system.
Thus, keep in mind the latest view of our globe, courtesy of David McCandless. He compiled this esoteric worldview, because every nation is the best at something, from a collection of global data sources.
Looks like the US is “best” at spam (not the luncheon meat). While Russia leads in, of course, dash cams.
