Uber is testing (?) an option to add drivers as your favorite so you can ride with them in the future pic.twitter.com/2BYm9RChCU — Jane Manchun Wong (@wongmjane) May 29, 2019

This would be a big change for the app -- and indeed Uber overall. On one hand, this kind of feature could pose a privacy risk for drivers, but if well implemented, could help bolster a sense of confidence and security among riders. Almost everyone who uses the service has a tale to tell about a past Uber driver, so if there's no way of straight-up avoiding particular individuals, this function will at least make sure you get a driver you're comfortable with.
