I lurk and lurk and never post here but... there are a couple of things that bug me (pun intended) in this discussion:
First off, ford has the largest fleet of autonomous cars in the industry. How are they behind the curve?
But my real problem is AI security. All computer systems bug and are vulnerable to virus attacks. Even if all the other variables are working wonderfully, what happens when the system shuts down, or malware screws the whole thing up, or do we really believe that nothing can possibly go wrong with Elon & co's super-systems?
