I agree that it's worth understanding that the law does not ask for any of this information to leave your car, so "federal surveillance tech" is a bit exaggerated. I have an unimpressive Honda Accord, and it will ding and display an alert if it suspects I'm drowsy.

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.

Since the rules don't seem to be in any real form of finality and the government largely exists at the pleasure of corporations these days, I am skeptical that Big Government is going to suddenly be forcing Elon to brick your CyberTruck if you have an imperial IPA.

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.
