I am always impressed and a little bit worried that some people I know completely rely on Google Maps (or competitors), even for basic navigation tasks like driving to some nearby village or getting to some tourist attraction in a foreign town they are visiting. With some of them, it is obvious that they don't have the mental representation of a city you normally would have after living/staying there for only a few days. I don't know whether this is sad / dangerous or even unhealthy for their brains, but it worries me enough that I make a conscious effort every day to only use route planning software to get an understanding what the optimal route would be. After that, I always rely on printed maps, general handwritten waypoints or just wandering around a foreign town in roughly the right direction.
