He's one of the top experts in self driving technology, a motorcycle he and a team built in college is in the Smithsonian. I can see Uber wanting to keep him on unofficially.
"He and a team" - I'd be curious to see the extent of his technical contribution, given that he's billed as the team leader and seems to be taking a lot of the credit here. In my experience, 'team leaders' who end up with the credit for the finished product do so because they spent all their time self-promoting rather than actually, y'know, building the product.
While I've personally seen examples of the team leader getting credit for being a self-promoter, I'm not convinced. I've also seen groups where the team leader was the most passionate, and really was the driving force for the project.
I do not know which he is, but I'm not in a position to pass judgement.
