Google and most other digital maps are indeed terrible maps. They are fine for a certain kind of navigation task, and great for looking up where the Starbucks nearest your current location is located, but for most other map uses, and certainly for actually getting a picture in your head of where you are or want to go, and how that relates to other things that you know or may want to know, or for thinking about an itinerary or even route that might be other than the shortest or fastest, they are terrible.
