Displaying ghost cars and false cancellations strikes me as fraud, at the very least.
I kind of doubt it. It's not like you enter into a contract with Uber just by downloading the app, and I don't think you have a legal right to use their services. Maybe you could drum up some sort of civil rights violation? But I don't think law enforcement is actually a protected class...
(1) a false statement of a material fact, (2) knowledge on the part of the defendant that the statement is untrue, (3) intent on the part of the defendant to deceive the alleged victim, (4) justifiable reliance by the alleged victim on the statement, and (5) injury to the alleged victim as a result.
1-4 seem obvious enough, but I'm not sure about #5. Would wasting their time or interfering with their enforcement job be enough to qualify as "injury"? Or, since they're acting on behalf of the local government, would it count as injury against that government due to not being able to prosecute crimes and apply fines that they would have been able to if Uber hadn't lied?
