Here is a better insight: don't user Uber. They have seriously become one of the most distasteful companies to give money to. Try Flywheel in SF, it is virtually identical to the Uber app, the drivers are way better, the app doesn't mislead you about driver location, there is no surge pricing, the waits are (in general) less, and drivers are just as polite :)

Wait what was that last part? Yes it is true. When I first moved to SF 4 years ago taxi drivers were unbelievably rude but the one good thing Uber has done is change the bar for customer service for the better and make rating drivers in an app a standard. The result is that there is no reason to use Uber in SF. I don't know the details of other cities but I know other major areas like NYC have similar services.
