I'vd said this before, but due to an extremely well-documented human bias, people will tolerate massively higher failure rates from humans than they will from robots. At least two orders of magnitude worse. Nobody really seems to know why, but it's a fact of human nature and we have to deal with it.You are reversing the meaning of nines. It is a guarantee of performance, not a guarantee of failure. 99.999% guarantees all but 5.26 minutes worth of a year's (continuous, non-stop) driving. Those remaining 5.26 minutes might be fine, but they are not guaranteed.
Flip it around, how many minutes is a typical driver "guaranteeing"? That is, what is the average failure rate for a human driver. If Tesla can really achieve five nines (which I doubt, except for limiting the circumstances) five nines is almost certainly better than any human driver.
I don't have the data to back it up, but if someone drove 60 hours a week, fifty weeks a year do you really think they would only make 1.8 minutes worth of mistakes? I think a reasonable person can accept that human drivers make errors far more frequently than that. The question is, when will Tesla be able to demonstrate 99.999% performance?
[edited to make more evident the part I was responding to in the quote]
So, given two options:
-- A robot in charge, where 1 person dies for every 1,000,000 instances
-- A human in charge, where 100 people die for every 1,000,000 instances
People will collectively choose to have the human in charge. :shrug: It is what it is. Musk has made some statements indicating that he understands this.
My point is "better than a human driver" is irrelevant legislatively.
You can get around this psychology by only offering "driver assist" features, leaving the human clearly in charge.
