alt Hacker News> I doubt judgement is heavily impaired at 0.05 BAC
Physical coordination becomes an issue. 70% of subjects tested struggled to maintain lane position at 0.02%.

Is this something that has been rigorously studied? Like multiple follow-ups?
This article is from 2002 - twenty years ago. It cites several other studies, which seem not great overall.
One studied a driving simulator, the others looked at deaths in the single year after lowering blood alcohol.
The one about minors in Maryland seemed especially strange, as minors are usually required to have 0% BAC.
It sounds like cherry picking.
That’s not what your link says; impairment at 0.02 BAC is measurable, but a fraction of standard day-to-day variation for a person. It’s roughly equivalent to missing coffee at breakfast.
I don't see how that relates to, say, software engineering or physical pentesting though. And 1/3 people is still a fairly significant number that do not suffer ill effects. I also said heavily impaired—not that they were categorically not suffering from any effect of the alcohol.
My point is not that they definitely should have done it. It is simply that, in this context, it's really not a big deal & is not really germane to the discussion at all. They did nothing wrong, stone cold sober or not.
