This isn't a self-driving car. It's a driver assist. It depends on an alert driver behind the wheel. What we're learning is that these systems can, in some circumstances, be the worst of both worlds --- a human driver lulled into complacency by technology that was not designed to handle complicated road conditions autonomously --- a system that itself generates both human and machine error.

There's an interesting similarity with Air France 447 in your description -- a crash caused by information overload and the normal assist system going into an alternate mode.

Noone is arguing about the benefits of self-driving technology in general.

The question at hand is: Does this specific piece of equipment actually work as described, and move us towards that goal, or is it a piece of cobbled together junk that will cause more accidents? If you want to sell this specific piece of equipment on the consumer market, you'd better have a good answer to that question, and be able to back it up with more than "hey, it worked for me this morning!"

my god, idlewords couldn't have written this better
