Recently I saw this.
I am actually surprised how they know quite good, compared to for example me and people I know, most of us can name barely few states. Some even knew where is Croatia
Out of nothing I'm not sure I would even be able to label half of the USofA correctly (although I'm pretty sure we never had to learn this in school) and I always mix up the baltic states. : (
Most of those maps you linked were filled out quite decently. Of course interview compilations etc. never show the boring people who were mostly right about anything they were asked, so an imagination is produced that you have to wonder how half the western population is even able to survive everyday traffic.
