Last week I did 72 trips and only 6 pax new that they get rated by their driver. I'm afraid to educate the pax on the rating system in fear that I might receive low ratings, I'm a 4.94 with 1477 trips completed.
I've learned to stop picking up the bar crowd when my rating starts to dip. I have a 4.9 rating with 3200 rides on Uber and 900 more Lyft. My advice if you want to drive late back off when you see your rating drop. I hope there's enough business in Vegas to justify working days. I'm personally tired of 70-90plus hrs a week.
