Here's what I mean. There are people who will drive drunk. At the margin, there are people who will not drive drunk, but who will drive drunk using FSD. But how many? How much more drunk are they willing to be?
On the other side, driving drunk with FSD is safer than doing it without. Criminally irresponsible, yes, but I think reasonable people will agree that it's somewhat safer, FSD has a better track record than drunk drivers. But how much safer?
Depending on how the margins intersect, FSD is either more dangerous or less so. I suspect the answer is less so, that is, there aren't that many people who would only drive drunk with FSD, and FSD is good enough at what it does to lead to fewer accidents. But I can't prove it, and reasonable people might come to a different conclusion. Practically speaking, it's impossible to get data which would settle this question.
