This is pretty bad from a hardware/software verification perspective. People who care about correctness can just go home, I guess. It's amazing that we're gonna let these things on the streets. When you weigh almost 2 tons and can go >100mph, it doesn't matter if you have a gun mounted on you or not, you are a weapon .
It only has to perform better than a human.
A person can explain "why" they did something when an accident happens. I've spent a lot of consulting hours helping unwind the "why" of ML/AI models, and we bill regardless of whether we can actually find that answer.
Putting aside by personal bias that I think Tesla is functionally incapable of doing anything well, lets pretend they deploy FSD - I think the fact that in that 1 accident to every 100+ human accidents you can't find "why" will override the fact that there are xx% less accidents.
Just from my experience consulting in healthcare and working with actuaries during the Obamacare debates and modeling out the impact of that -- people just honestly aren't open to statistical arguments when it comes to human life or emotional issues.
(Not saying they're wrong, me and my wife completely disagree about so many issues where it's emotions vs statistics, I think she has a very valid point on many of those - what I'm trying to say is this is going to be a philosophical debate more than a statistics debate so Tesla should gear up accordingly).
