Impaired Driving Prevention Technology Sounds like a good idea?

Advanced Impaired Driving Prevention Technology
Distracted Driving:
NHTSA defines “driver distraction” as inattention that occurs when drivers divert their attention away from the driving task to focus on another activity.
In general, distractions derive from a variety of sources including electronic devices, such as navigation systems and mobile phones, as well as conventional distractions such as sights or events external to the vehicle, interactions with passengers, and eating or drinking.
Section 24220 defines “Advanced Drunk and Impaired Driving Technology” as a system that
(A) can—
(i) passively monitor the performance of a driver of a motor vehicle to
accurately identify whether that driver may be impaired; and
(ii) prevent or limit motor vehicle operation if an impairment is detected; or
(B) can—
(i) passively and accurately detect whether the blood alcohol concentration of a driver of a motor vehicle is equal to or greater than the blood alcohol concentration described in section 163(a) of title 23, United States Code; and
(ii) prevent or limit motor vehicle operation if a blood alcohol concentration above the legal limit is detected; or
(C) is a combination of systems described in subparagraphs (A) and (B).97
This means that a final rule could require vehicles be equipped with a system that detects whether the driver is impaired (an impairment-detection system); a system that detects whether the driver’s BAC is above a specified threshold (a BAC-detection system); or a combination of these two systems. These options and the technology that might fulfill each option are discussed in greater detail later in this document.
NHTSA reviewed several available and prototype camera-based driving
monitoring systems that publicly state the ability to monitor aspects of driver state, including driver’s eye gaze, eyelid/eye closure, pupil size, head/neck position, posture, hand/foot position, and facial emotion during the driving task.
