They don't get paid more but they'll be chosen first when a user requests a ride (I think they also drop low-star drivers)

Does Uber make efforts to increase star ratings for drivers or is it all up to the driver? I was a quality manager for a call center and bad ratings can happen to even the best people. We always worked with them to improve for the future. We also did not rely exclusively on customer ratings and used internal QA. Does Uber have internal QA for drivers?

My under standing was if your star rating is too low then you lose your job as an Uber driver. They use it as a stick not a carrot.
