My point is not that a drunk "should" drive, even with FSD. It's that clearly they do. I know someone personally who drives under the influence frequently despite the legal and material risks. No one thinks this is a good idea.
I would absolutely prefer any driver using FSD, but especially one physically and mentally inhibited by drugs or alcohol.
> I include 'thinking the Tesla will just handle it' as under the influence.
I've commented on this before, but: no one using FSD for even a short period of time is "under the influence" of the branding. The lived experience of the technology is that is amazing and useful, even if it flawed. YMMV
