I don’t like this at all (from the email).
In-app tipping is here. From 5-star ratings to compliments, and now with tipping, our app gives you many ways to say thanks. To ensure a smooth, uninterrupted ride, you can tip drivers after your trip at a time when it’s convenient for you. Tips go directly to drivers; Uber takes zero service fees.
I am a frequent Uber user. One of the selling points for it is the ease of use and the fact that I can grab a ride without the need to carry cash or tip. I did occasionally tip, but only if the driver did something out of the ordinary (like stop at a shop or run through a drive through for me). There was never, however, any expectation of a tip.
The problem is that while Uber has a rating system where I can rate the driver, it also has a rating system where the driver can rate the passenger. The intent of that is that if a passenger is abusive, messy, drunk, or just gross, a bad rating will discourage other Uber drivers from having to put up with a bad passenger. Eventually, bad passengers will never be able to get an Uber ride.
Now that there is tipping, however, there is an incentive for the passenger to give big tips – even when it is undeserved – just to prevent being blackballed by bad ratings from grumpy drivers. Uber should have one or the other. Either have tipping or do away with the passenger rating system. Having both promotes undeserved tipping. It also increases the overall cost of using Uber versus other transportation alternatives.
