Yes. From what I understand, the Grenadier monitors your inputs to the steering, and if it detects inputs that the software identifies as associated with "drowsiness" (or drunkenness) it will alert the driver. Here is the snippet from the Grenadier website:
It appears that some form of this software will be mandatory in all new U.S. vehicles beginning in 2026 (it was originally scheduled to begin in 2024). This mandate derives from the The Infrastructure Investment and Jobs Act, passed by the Biden administration. Below are screen shots from the law which cleared the House of Representatives on Jan 3, 2021, and became law on November 15, 2021.
The official designation of the law is:
PUBLIC LAW 117–58—NOV. 15, 2021, and you can find the full text here:
The screenshots come from Section 24220: Advanced Impaired Driving Technology
EDIT: I just found these descriptions of ADAS, from the Grenadier website:
Safety Features
ADAS (Advanced Driver Assistance Systems) features come standard in the Grenadier to help keep you safer on the road. These features include:
- Lane Departure Warning (LDW): The Forward Facing Camera in LDW monitors your lane and alerts you with an audio and visual warning if you start to drift. This feature helps you stay on course while driving.
- Automatic Emergency Braking (AEB): AEB uses camera sensors to evaluate traffic and road conditions, alerting you of potential hazards and automatically applying the brakes if you fail to respond in time. This feature responds promptly in critical situations. (*System does not react to pedestrians, cyclists, scooters, or animals. )
- Intelligent Speed Assist (ISA): ISA uses camera sensors to detect road signs and alerts you when you’re exceeding the speed limit. It also refers to high-quality maps when signs are not visible.
- Driver Drowsiness Detection (DDD): DDD monitors your alertness by analyzing vehicle systems and an official sleepiness scale, alerting you when it’s time to take a break. This feature is useful for long drives and late nights.
