To be honest, it's just a little sad that reading this article it seems that Hotz hasn't grown up much, and that attitude isn't great to see from a person working on a safety critical application. If you want to put your hands in the life of George Hotz fine, but keep the hell away from the public roads.
Comma implemented driver attention monitoring into their device before Tesla did, and George had been advocating Tesla do it for a long time before they finally did. He talks about this in the most recent podcast with Lex Friedman.
That doesn't sound like someone who is too immature to work on a safety critical application to me.
