humans at least are aware that they made a mistake and can avoid collision. Tesla makes no mistake, tesla has no idea whats going on so you cannot call it a mistake. Its not a bug, its a feature.
So instead of a single human learning "gee, shouldn't do that again", 100k+ vehicles learn about it.
First we had the barrier crash. Then there was the video of someone reproducing the barrier crash and manually emergency braking. Now we have this video. One thing I've learned in my software career is that if one of our customers reports a bug, 10,000 others have encountered it but not bothered reporting it. So why hasn't Tesla rolled back the software yet?!
