I'm not really driving too much because it's Aug. and Sept. but last week I had 6 rides, all rated 5 stars. Yet my average star rating went DOWN!!! Along with tips on how to improve like: Starting/Ending Trips On Time, City Knowledge and Professionalism. What da bleeeeeeeeep!!!! Anybody ever had that crap happen to them??? I e-mailed UBER for an explanation aaaaaaaand..... you guessed it! Canned, robotic response!!
