raises eyebrow
That is a) a disturbingly weak answer against b) a disturbingly weak metric.
The better questions, which you are probably too biased to answer (this is not particularly a condemnation of you personally):
1. How many times in the last year have you gone into microsleep while driving?
2. How many times in the last year have you done other tasks while driving (eating, texting, gotten in a deep conversation with a passenger or third party, etc.)
3. How many times in the last year have you been in extremis while driving (i.e. where immediate drastic action was needed to prevent an accident)
Here’s what we know from literally decades of human factors research, accidents, and near misses.
1. Humans get bored really easily.
2. Bored humans get distracted or nap.
3. Humans take for bloody ever to get up to speed (reaction time while paying attention is ~0.25 s, while not it’s 2-15 seconds). It gets worse when humans are tired.
4: Humans are really, really bad about normalizing deviance. (As in, based on familiarity we push the envelope and erode safety margins)
5: Humans believe they are much more capable than testing shows.
So while you claim to be, and (giving the unverified benefit of doubt) might be a 6 sigma safest driver, the 200 humans next to you also claim the same thing erroneously. Thus, the human factors engineers tell the systems engineers that the driver alert system is safety critical, and not something for end users to “adjust”.
