FYI, I received notice from Uber yesterday that me and my vehicle had been selected by City of San Diego/Airport Authority for "random" check based on the last 4 digits of my license plate number. Uber asked permission to provide the City my info including background check info. Failure to provide/agree would mean no change to our partner relationship other than I could no longer pickup at airport. I provided approval and for some reason Uber came back and said I am going through another background check..don't think this is true as I have been driving for over a year and would think City would want to see an original check. Though it is interesting and just wanted to share with other drivers.
