Interesting post, but I disagree with the conclusion that with a bit of work AI could take down the best Geoguessrs. The best players already take into account all the metadata like camera quality and distinctive features of the Google car. Furthermore, they would surely have an edge in urban locations where proximate locations are visible in street-signs. I could be proven wrong though, and it would be super interesting to reverse engineer AI guesses that turn out to be surprisingly correct based off little info.

To see just how good the top players are at instantly recognising a country using these clues, then check out https://www.youtube.com/watch?v=zEmoAYpTJuA . Or maybe don't if you don't want the game spoiled!
