Favorite Driver is a feature available in the Uber app. This feature will allow riders to mark drivers as a "favorite" after taking a trip. If one of your customers marks you as a favorite driver, you will receive a notification in the driver app.
Drivers who have been marked as favorites may get the opportunity to schedule trips with that rider. If the rider who has marked you as a favorite driver schedules a trip more than half an hour ahead of the trip time, the driver app will send that trip to you before anyone else.
