Re: Wrong question
That's the point, yeah. ADAS is worth using for me if its accident rate is less than my own non-ADAS accident rate.
Problem is, nobody knows any of the numbers there. I don't know what my own non-ADAS accident rate is, beyond "low", because I don't have enough samples. I believe I am a good driver, but it's well known that everyone overestimates their driving skills.
I also don't know what the ADAS accident rate is, but that's more annoying, because whereas my own numbers are mathematically unknowable due to not enough samples, ADAS numbers should in principle be possible to have with some confidence. But we still don't have them.
Which leads me to conclude that I have to agree with you: with this much smoke, ADAS needs to actually be overwhelmingly better than average, in order for me to be able to be certain that it is at least somewhat better than average. I won't use a system that's "quite a bit better than a drunken madman". Actually, just like everyone else, I believe I'm a solidly better than average driver, so I won't even use a system that's "somewhat better than average". It doesn't take much to get to requiring 10x better, yeah.
The only bit I disagree with is that it's better to die by own stupidity than by a computer's, because my own stupidity is preventable. Yes, it's all preventable, but no, statistically, it doesn't all get prevented. That number can be made very low by careful driving, but it's not zero and only a fool would pretend it's zero. It is a positive number, which could in principle be compared to another positive number. The color of the dice I'm about to roll doesn't really matter.
The very short version of this: yeah, I agree with you, but what if autonomous vehicles were already 10x better? I don't think they are, but if/when they will be, I still won't know, because the damn numbers are not available anywhere.
