I've driven Uber for less than a week. As of this moment, my app shows the following statistics: 4.62 Current rating. 42 total trips. 26 rated trips. 20 5-star trips. No issues reported by riders. Now, I can remember two or three trips that had issues - on one I really messed up on the route - so I don't expect perfect ratings all the time. Yet, I have no clues as to what I can do to improve my ratings. My car is clean. I dress reasonably decent (tunic / sweater and leggings). Folks are always pretty cheerful. Any suggestions? What can I do to find out what I'm lacking? Or, to plant the idea of a 5-star rating in their minds? BTW, I've only had reason to rate three passengers at less than 5-stars. They got three stars, and the main cause was making me wait - then complaining that I wasn't getting them "there" fast enough.
