The legal battle Waymo waged against Uber is getting more and more intense, and the Alphabet-owned division is showing no signs of slowing down. It has just accused the ride-hailing company of covering up a trade secret theft in a new set of court of documents. Waymo says Uber hid a Light Detection and Ranging (LiDAR) device -- the system that serves as self-driving cars' "eyes" -- that former Google engineer Anthony Levandowski developed based on its technology. If you'll recall, Waymo filed the lawsuit after another one of its engineers revealed that Levandowski downloaded 9.7 GB of confidential materials related to its self-driving system before leaving company. He then established Otto, the autonomous truck company that Uber ended up acquiring for its own self-driving ambitions.
