Uber chief product officer Jeff Holden planned to announce (WARNING auto play video) at the Web Summit conference in Lisbon today that Los Angeles will join Dallas as the first two cities to host the company's proposed network of flying vehicles. He said the company expects L.A. residents to be making "heavy use" of the service by the time it hosts the 2028 Olympics. I know Uber has Nasa on board for this effort, but 2020 is only a couple of years away. Sound to me like they are being overly aggressive with this projected roll out of service. I hope they get it right. "Technology will allow L.A. residents to literally fly over the city's historically bad traffic, giving them time back to use in far more productive ways," Holden said in comments shared with USA TODAY. "At scale, we expect UberAir will perform tens of thousands of flights each day across the city."
