We don't know where we are. We're in a car, looking at other cars, roads, structures, tunnels – wasteland. Position? The Global Positioning System informs us, with its horde of satellites, orbiting Earth. Guiding us with its synthesised voice, transporting us, 'translating' us. Telling us what to do. "After 250 meters, keep to the right on the Brudermühlstraße, then keep to the left." (And so on, and so forth.)
