Lyft is allowing riders to use the ride-hailing company's app to add an extra destination for two-stop trips. You put your first stop in as the destination when requesting your ride, and then tap a new “+” icon next to the destination to add a final drop-off location. Lyft will also let you change your mind and remove the stop if you decide against whatever it was you were going to do. Uber, Lyft's largest competitor, does not offer the ability to add an extra destination.
