Uber has gamification dynamics for both their drivers and their users.

On Mexico there's a dynamic called Uber Tacos, where every time you order an Uber on September 16th (Mexico's Independence day) the driver will pick you up with an order of tacos, this makes the user want to use the car service in order to be part of the group that got tacos.

For the driver there's a dynamic that makes the driver want to keep driving in order to collect badges, if for example the user had a good experience with the driver they will rate them and when the rate is good enough they will acquire a badge, when they get a lot of badges the app let them know before other drivers that there are users in search for a car; also before the current ride is over they can already see other upcoming rides, and for them because of the badge dynamics and the app psychological technics is more easy for them to accept the ride than to say no, just because the button is bigger and brighter by saying yes. The more rides you get the more points and badges you collect which gets you to a higher rank.
