The real failures that I worry about that humans would never do are things like: Terrorists find a zero-day and make every Waymo suddenly do a hard left turn at full speed all at the same time.
Like that scene in "Leave The World Behind".
Still a fan!
My parents are convinced that they're not safe enough. My wife is convinced that they're too safe because they keep blocking the two-lane causeway near our home when they're not willing to drive through sketchy construction areas.
It took Waymo more than a month of nearly daily attempts before it could figure out which way its cars should drive into the driveway at my apartment building. For a month straight, one of them would drive in through the exit at our building and then get stuck waiting for some remote human to rescue it. I will never understand why that happened more than one or maybe two times.
I'm still a big fan! But wow, what happened there.
