Last scandal at my hometown, that is unlikely to reach the English speaking world, is as follows.
Our airport, which lays on federal grounds, grants a monopoly of transportation services to certain well established company. Not even city taxis are allowed in (they can drop passangers, but cannot pick up anyone else while they are on premises). Uber attitude towards this situation is the standard one, basically an extended middle finger to every law, institution or authority of the land.
The problem is that if airport security catches an unofficial taxi on premises, they call federal police, the car is taken to a seized and the driver cannot recover until he's paid a very considerable fine (think several months of blue collar wages). Uber strategy to deal with that is to swarm security, so they always catch someone, but the process to deal with the offender is very time consuming and all other Uber cars are free to do business while the guards are preocupied.
Uber will punish any driver that refuses to take airport calls with bad karma, and will "gratiuouly" pay for your fine... once (if you get caught twice, it is on you), but they will not pay you any wages while your car is locked in federal grounds (a time that is measured in weeks, not days). They will also not pay for any damages to the car itself, which unfortunatelly is a rampant problem in this country when vehicles end up under the custody of the government.
So, be very glad to have a car and a chauffeur at your fingertips beck and call, but please do not assume the driver is enjoying it as much as you do.
