You do realize driving tired is more dangerous than drunk
This!
I'll have to admit to having driven my car after having had at least one glass too many - so, impaired, but not out cold. On the rare occasions this happened, I did not have any trouble getting home safely.
A couple years back, I went for an observation night an hour's drive away after having had another astrophotography session the night before, i.e. not much sleep. The session was fun, we had some public, and after the public was gone I used the opportunity (hey, the sky was way darker there than what I'm used to) for another short astrophoto session. After, another hour driving home. Trouble was, it was quite hot, and my car's air conditioning didn't work properly... boy, I thought I'd never get home. Even with windows open, I had a very hard time staying awake, not a drop of alcohol in my blood but instead a coffeine&sugar beverage. I didn't really want to stop for sleeping, with quite some expensive gear in the back and obligations the day after. That's been my single worst peace of driving, ever, and I'll make damn sure that never happens again.
That said, it will be a cold night in hell before I trust some "AI" to drive me around. I can't really fathom why the industry thinks autonomous cars are actually wanted by their customers... unless they consider normal drivers as "not-their-customers". IMHO, they'd better develop a simple reliable battery-electric vehicle with good range without fancy gimmicks, to sell at affordable prices. Any gadgets that supposedly will help the drivers will only tend to make them worse drivers as they rely on these gadgets - thus better not have them and keep drivers alert.
In case anyone wonders: my driving lessons were from a place very near to Germany, with quite the same philosophy.
