If I don't know where I am on the map, what use is moving pins around going to be?
Case in point -- I was in Las Vegas recently, and made the mistake of calling Uber from under the covered walkway at a large casino/hotel entrance. The driver ended up being dispatched down a back road leading off into the desert behind the hotel. Because the map showed nothing but nearby streets, there was no way to tell that it was reporting my position incorrectly.
In the satellite view that's normally available in map-based applications, it would be very obvious that my reported location was nowhere near the hotel entrance.
