I am driving Northeastern New York, primarily Lake George. The Uber navigation app is not good up here. At times the address is correct but the nav sends me to another street. Lake George is filled with small resorts and hotels on hills or down side roads next to something else and the Uber nav will absolutely misdirect you. My advice: call your rider immediately after accepting the trip or a couple of minutes out to confirm their location. Uber stresses that people don't want to be called, but I don't think this is the case up here in NY(based on my limited experience). I tried sending a text "I am at the pickup location" but it was often the wrong spot, so I switched to calling. No one has complained(so far). My rating is 4,98 on 50 trips
In my area, there is very little cell coverage unless you have Verizon and even that is not great. I am running a Garmin GPS as a backup to navigate all the time and it's critical when cell service drops out. It has saved my bacon a few times I was so far up 'yonda I had no idea where I was. "Go Home" got me to somewhere I was familiar with. I have had trips to Luzerne and Brant Lake where there is no cell coverage at all. GPS still works, so I believe the Uber app calculates the trip based on the GPS coordinates and when I end the trip in the app, caching the data until I get coverage.
Just a FYI: most of my pickups here are 10-15 minutes away and unfortunately, that means you may be deadheading 25+ miles before you can even accept another trip. I am not making much at all, even with promotions.
