Word on the street is bc drivers have been joining uberx to "sabotage" it. Dont know how many but apparently uber is aware of this and trying to find ways to track these nasty slobs. I am also thinking this is why onboarding stopped for a while, there must be some stricter requirements in place now. Come on uber... when you making the final kill move against these pigs?!? Put them out of their misery & finish them!
