The only way this works over the long term is to force out competition so that they can massively jack up prices, and/or replace drivers with self-driving cars that have lower costs.
If Uber does this and they realize customers are not riding as much anymore, then it is a problem with their pricing and setting of expectation.
Is their any data to back this up? Outside of Hacker News, I don't think I've ever heard someone complain about tipping. I have no problem with it.
I think most people's view would change if they were in a situation where tipping makes the difference between being able to pay your heating bill.
Tipping, as it exists in the US, is pretty much a dark pattern.
I think most people hate tipping because they hate when people ask for tips. But a formal tipping system might reduce the number of Uber drivers who already ask for tips.
I tip 22% for full service, 10% for partial. If I go to the bar, I tip 10%, or a dollar/drink if I'm paying cash. If I'm ordering takeaway somewhere, I tip around 5%. I have no idea which of these are reasonable or not, because there is no "tipping class". I have no idea if places I regularly go like to spit in my food because I tip like shit.
Can you explain the math? Why is this amount higher than 20% rather than lower than 20%?
According to who? Certainly many restaurant workers in the U.S. earn most of their income from tipping.
