We need to compare against the real human error rate (including drunk drivers, sleepy drivers etc). What is that error rate?
Also, fault tolerance error rates don’t work that way - difficulty increases exponentially as you increase fault. In other words, it’s much more difficult than three orders of magnitude to go from 3 9s to 6 9s - it’s easily 5-6 orders of magnitude.
yes, the long tail of difficult event is exponentially more difficult to handle. That's why I said above that people "feel" it is ready but it is nowhere to be even close to ready.
The average crash rate for human is one every 500k miles.
When you're playing candy crush and FSD kills someone, whether or not it's drives better than the average driver is not something the judge and prosecutor are going to consider.
First, that’s because FSD is legally only L2 and thus legally you are required to pay attention. It has nothing to do with the engineering realities of the impact on improving safety.
When L5 becomes available then this becomes a different calculus. And it’s honestly questionable about how good the characterization actually is since Tesla’s L2 FSD seems to outperform Mercedes’s L3 and it’s more a matter of the liability the manufacturer is willing to take on vs objective measurements of quality.
