Facing growing pressure from labor unions and regulators across the U.S. and key overseas markets, Uber on Monday introduced a series of new apps and benefits for its core group of drivers. The goal is to make their working hours more productive and profitable. Among the new apps are Driver Destinations, which lets drivers input their destinations twice a day to restrict ride requests to their current routes. Uber has been testing the app in a few cities and will roll it out to at least a dozen more this week and worldwide in the future.
