If you use Uber every day, or use it very frequently, and you know that the app does not accurately pinpoint your location, then contact the driver and tell them that. Don't get in the car and complain about the app and how doesn't pinpoint your location when you could easily contact the driver and tell him through text or phone call where you would like to be picked up. Especially when I have been sitting and waiting for the rider for several minutes and they finally call and say, "where are you? I'm waiting for you." This is AFTER I have attempted to make contact with the rider when I arrived, and they ignored texts and calls.
