All of the above, plus: Taxi drivers, at least herearound, have mandatory rest periods, which are very strictly enforced. I know that for a fact, since my girlfriend used to drive a cab. Even if you adhere to your rest period (and can prove it), but don't have the paperwork straight this can lead to hefty fines. There's nothing stopping your friendly Uber driver to drive you around after two back breaking shifts at the factory. He may even quaff a couple beers, or three, before starting his "Uber shift". Something which is an absolute No!No! for a licensed cabbie. They have very stringent zero tolerance rules when it comes to booze. Your Uber driver does not. I can't speak for the rest of the world, but imagine that this situation is quite comparable to a lot of places.
