Real quick - I do not agree with Lex's concept that humans are too unpredictable such that an autonomous driving vehicle cannot account for a stupid ballistic choice.  I will note that what is extremely hard to do is to identify what is important from moment to moment.  So, for instance, can an autonomous vehicle eliminate all risk?  No.  Can an autonomous vehicle do as well as a human from a risk POV. Yes and so what we are really arguing is can an autonomous vehicle outperform a human from a risk POV and I answer Yes. Again, it is all about detecting what is important from moment to moment and that is something that can be taught/programmed.  It is all a matter of time and data and dedicated human effort.  That was a good interview Lex.  Try inviting him back.
