At the moment, only Uber employees in San Francisco and Los Angeles have access to the feature. The ride-hailing giant is still in the midst of testing it, and a wider release might depend on the trial's (and future tests') results. The spokesperson said, however, that "Affordability is a top reason riders choose shared rides, and [they're] internally experimenting with a way to save money in exchange for a later pickup." Hopefully, that means there's a big chance that the feature will make its way to all users' apps, because it's not always easy guessing when it's the best time to book a ride.
