My (not GP) issue with him comes from all his whining over the NHTSA stuff. You can't talk about how easy the problem is and how much better you are, and then fold when safety regulators show up. That to me says that he may be incredible at building things, but doesn't know how to take it the last mile. Sure, you can argue against the regulation, but I for one think that self driving cars should have strict safety regulation. And from what I read they weren't asking anything crazy of him that they wouldn't of anyone else.
