Thank you for the response.

The question is, if it really is a win-win, which leaves both Uber and the driver better off, why is there anything untoward to it?

Whenever anyone is being nudged, there is (as far as I can see) no reason to believe that the choice made goes against their preferences.

Would you say that charities using similar nudges are equally “evil” as Uber?
