Heh, you have no idea how lousy Google Maps data really is until you go somewhere away from big cities and countries which Google cares about. In the remote corners of Greece for example, it's completely normal to find nothing in a spot that has a supermarket. It's either in the wrong location, mistranslated, closed 5 years ago or never was there and is just maps spam. Often squinting at the satellite data offers more of a clue where the paths are and sometimes you can glean a shop sign from above. We've had similar experiences in thinly populated areas of Galicia (Spain), Sardinia and Sicily.
