I'm not sure I understand this at all. You can move a pin to set your exact location in Uber and Lyft, you don't need to rely on GPS at all. Whether the directions supplied to driver get them there are accurate doesn't depend on GPS.
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.
Around here, the "satellite" imagery seems to be captured by people flying small planes back and forth.
And yes, that's absolutely true. I've been on streets that are right underneath bridge decks and drivers can't find. One way to avoid this is to set your pickup location to a business if one exists (i.e. a bar, hotel, restaurant), so the address is correct.
What I was hoping for was a comment like, "Hey, dumbass, press [...] and it'll turn on the satellite view. Everybody knows that."
