Uber is offering sign-up bonuses and other incentives for drivers as it faces record demand for rides and meal delivery. The San Francisco ride-hailing company said Monday that total monthly bookings, including food delivery and passenger service, reached an all-time high in March. In a government filing, the company said demand for ride-hailing, which plunged during coronavirus lockdowns last year, has recovered more quickly than expected as daily COVID-19 vaccinations exceed 3 million per day in the U.S. Passenger bookings reached the highest level since last March, when spiking infection rates began to shut the country down.
