This sort of nonsense is well studied in aeronautical world, and will lead to too many alerts, which, in turn, lead to predictable outcomes: https://flightsafety.org/asw-article/normalization-of-devian...
Sure, don't nag a pilot who is already very well backstopped by the existing solutions. Your uncle coming back from the bar at 2am doesn't have any of that.
This kind of counter-intuitive/smarter-than-the-obvious pontification is a HN smell to me. Most of the time the obvious solution is correct. Driver attention management is one of the biggest (maybe the biggest) contributors to accident rate, and IMHO probably deserves some assistive technology attention. If the reverse is true, it needs actual evidence and not an attempt to reason from aviation evidence (a regime where inattention is NOT a major problem!).
