"Which way?" - "Wait, I'll go and check GoogleMaps..." Such dialogues take place countless times a day. We have long been used to being shown the way by apps and navigation devices. Without them we would be disoriented and lost. But this is exactly what happens quickly when you move outside the public space - on private or company premises, for example. These are at best incompletely captured in GoogleMaps or other software - they are literally white spots on digital maps. More information here!
