>Transportation isn't a service where it's acceptable to have good drivers who get paid more and bad drivers who get paid less, no matter what mechanism implements that pay differential. There should only be "good" drivers. Of course, there's no universal authority on what "tipping" actually means but I think many people (both the riders & drivers) understand that tipping is for the "service" portion that's not related to the driving. E.g. carrying the suitcases, pointing out the landmarks like a tourist guide, etc. The "driving" component of getting from point A to point B in a safe manner, without making incompetent U-turns, etc is the baseline. The tipping isn't for that. E.g. I usually don't tip the Hertz/Avis car rental bus driver but if I'm trying to carry 3 bags and he helps me with them, I will tip him. All that said, it's possible that some Uber drivers want extra tip money just for the sake of extra money. Like others, I also prefer transactions where there is no tipping expected. It would be annoying to scramble for some loose dollar bills to tip the flight attendants as I try to rush off the airplane to make a connection.
