Many vehicles, IIRC including Teslas, already have this safety feature.

Tesla does absolutely nothing like this. The closest things are that it'll kick you out of AP/FSD if you're screwing around with your phone, and it'll advise you use AP/FSD if you're driving manually and pinging between lane lines.
It’s also a hypothetical at this point because the system doesn’t exist, and there’s no consensus about whether it’s “fail open,” vulnerable to a centimeter square patch of electrical tape, or if it can randomly brick your car when it has errors. I would bet on the former.

But this law would step beyond that. It does require that the car "prevent or limit motor vehicle operation if an impairment is detected."
I'm not a transit safety expert, but that itself seems potentially dangerous - even just limiting speed, if it happens on a highway, could be difficult to handle. And of course, the detection systems will have false positives.
My prediction is that, in the end, this is simply going end up being a system to steer you off to the side of the road if you pass out at the wheel.
That makes it worse, not better. Contrary to popular belief, "$BAD_THING is widespread" is not a defense of $BAD_THING.

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?
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.
