I too used to drive (1970s/80s) well p*ssed; probably several times the limit - like so many in those days - and I never did anything remotely as dangerous as when driving when tired.
Fortunately, flying is different in that most of the time one does not need to pay attention to anything. Autopilot on, and there is plenty of time to think and act. In fact this alone can send one to sleep - nothing worse than crawling at 150kt across N France
