Oro Mobility and Uber Power the Hertz Surge Hertz announced via a Business Wire press release dated April 30, at 8:00 a.m. EDT that it has launched an affiliate operating company called Oro Mobility (Oro). Oro and Uber Technologies (NYSE:UBER) unveiled two strategic fleet partnerships. The first is autonomous robotaxi fleet management. Oro will support Uber’s autonomous robotaxi program of Lucid Group (NASDAQ:LCID) vehicles equipped with Nuro autonomous vehicle (AV) technology, handling charging, maintenance, repairs, cleaning, and depot staffing. The service is expected to launch in the San Francisco Bay Area later this year. The second is a driver-led fleet program already active in Atlanta, Los Angeles, and San Francisco, with Northern New Jersey expected to launch this spring. Oro supplies the vehicles and the drivers on the Uber platform. Hertz CEO Gil West asserted, “Hertz has spent over a century mastering complex fleet operations at scale, and Oro is how we put that expertise to work in the next era of mobility.” Uber Chief Operating Officer (COO) Andrew Macdonald added that the partnership will “help us continue to bring the best autonomous technology onto the Uber platform and accelerate the transition to a hybrid network.” Avis Stock Declines After
