The self-driving car's family tree

Key engineers and executives from pioneering companies such as Google and Tesla have jumped ship to form their own self-driving startups, such as Lucid Motors and Otto. Google's program, in turn, was shaped by a handful of engineers from two universities: Given the high stakes, it's not surprising that some of the companies where these engineers landed don't get along. Both Tesla and Waymo accused their former employees of stealing trade secrets (Aurora denied the allegations and Uber said it is reviewing the suit). Here's a partial family tree of the self-driving industry, showing how some of the key players have moved from one company or school to another.
