The Biggest Threats to Uber's Future, Ranked

Editor's Note: This story was originally published on May 9, 2017. It has been updated to reflect developments including Uber's firing of 20 employees following an internal investigation into its corporate culture, as well as self-driving engineer Anthony Levandowski. If you haven't heard (maybe you've been toiling in Elon's tunnels?), Uber has had a rough start to 2017. The Department of Justice has launched a criminal probe into the company's use of "Greyball," a system it used to identify regulatory officials and block them from booking rides. In January, it lost riders who objected to CEO Travis Kalanick's (soon abandoned) seat on President Trump's economic council.
