The technology that the NHTSA wants to mandate as soon as it is commercially available is not a warning, but "prevention". From the NHTSA report, page 3: "prevent or limit motor vehicle operation if an impairment is detected" - https://www.nhtsa.gov/sites/nhtsa.gov/files/2026-03/Report-t...
I don't know anything about Teslas - you were the one that wrote "Many vehicles, IIRC including Teslas, already have this safety feature". The $BAD_THING I was talking about is the one in the NHTSA report. I took you at your word that the two "safety features" were the same. My mistake.

in response to my pointing out that Tesla does something like this now. So I'm asking: why do you believe that Tesla alerting drivers that it looks like they're driving while fatigued is a $BAD_THING? Your stance seem to be a nonsensical knee-jerk reaction against a simple safety feature, so I'm trying to understand your thinking. Do you also oppose anti-lock brakes?
That makes it worse, not better. Contrary to popular belief, "$BAD_THING is widespread" is not a defense of $BAD_THING.
