No, the 2021 infrastructure bill required automakers to install passive technology (passive meaning not requiring any specific actions from the driver) to prevent drunk driving by some future date. However, such technology doesn't really exist yet.

Eh, with lane keeping features I don’t think it’d be hard to at least detect someone swerving a lot. Granted, I don’t think that would detect people that aren’t super drunk, but it’s something.

I might be wrong on that assumption - I don’t drink, myself.

As is commonly commented on by cartoonists: In plenty of places driving consistently within the lines might be the actual sign you're drunk. Because the roads/potholes are bad enough that you shouldn't be, if you value your suspension.

I live in a northern state so I certainly have experience with potholes, but I've never seen a road so bad that it would cause a false positive like that.

Our local dying mall though? Phew. It amazes me whoever owns the mall doesn't at least go out there with some asphalt themselves.
