Arttrans " Like I said earlier, most pax that do not tip get 4 stars. If everyone did this Uber would, eventually, look into why the pax ratings are going down."
The pax would have zero reason to put two and two together and make the connection that their four star rating was due to a lack of tip. They would have zero reason to make that connection. Uber tells them, there is no need to tip. As a driver, you are far more vulnerable to the punitive effects of pax rating drivers severely. Pax ratings mean far far less. They only mean something if it is rather busy.....
All you would be doing by that method is helping create a more severe, punitive rating system which offers zero meaningful explanation for anyone. In order for your no tip equals a four star to work, well they learn about their rating from/through Uber. Is Uber going to tell their pax " Sir, in order to make the experience more satisfying for our drivers, our partners, our records indicate that your rating as a pax is slacking, here are some things you can do to improve our partner's experience........ our studies indicate that 100% of drivers will give five stars t any ax who tips."
Unless Uber spells it out that clearly, what you suggest isn't going to have the effect you hoped for. What you describe is a kind of passive aggressive behavior. It is surely best to avoid that kind of way of relating to your pax for the simple reason it is bound to come back and bite drivers in the ass.
Drivers do not get to use the rating system to their advantage. It isn't designed to do that. All you would be doing is creating more chaos and trouble. You either need to be able to tell the pax........ they didn't put the pin in the right place, waiting more than five minutes is not cool..... cancel, collect five bucks and leave.
I read on here about a driver who dings pax for making him wait for ten minutes or more before they come out...... You don't ding a pax for your own stupidity. Same goes here: pax are told tipping isn't necessary. To punish them, no matter how good it feels, isn't cool.
