Is there something akin to a city's uber manager that all drivers have to report to for the sake of noticing if someone should _not_ be driving for uber?
I was thinking more along the lines of someone that notices something like "alcohol on breath", a person that acts as a customer's ally/mediator for corporate in cases of transgressions, an accountability person with little purpose than for corroborating corporate's opinions on "bad apples" (whether rightly or wrongfully) etc.
