Lexus Eye Monitoring Cameras Have An Issue: It Thought This Asian Man’s Eyes Were Closed While He Was Wide Awake
What if your commute was interrupted by a drowsiness warning — except your eyes are wide open? That's purportedly what happened to an Asian man driving a Lexus loaner, according to a viral claim circulating online. The specific incident couldn't be confirmed by credible primary sources. But the underlying technology failure it describes? Thoroughly documented across the industry.

Driver-monitoring systems are now standard across luxury and mainstream vehicle lines. Whether they work equally for every face isn't academic anymore.

How the System Actually Decides You're Drowsy
Lexus's own manuals reveal how the algorithm judges wakefulness — and where it admits its limits.

Lexus owner manuals confirm the driver monitor camera tracks three things:

face position

gaze direction

eye-opening state

When the algorithm decides your eyes aren't open enough, it warns you. The manuals also acknowledge the system can fail when the camera can't capture your full face correctly — a candid admission that the hardware has limits.

Lexus manuals confirm eye-opening state is an active detection variable, and that incorrect seat or steering-wheel positioning can cause warnings or reduced operation. Independent reporting, including coverage by CarScoops and CarBuzz, has documented similar systems triggering false drowsiness alerts on some Asian faces. The mechanism behind these failures is a fixed threshold — a single cutoff number the software uses to judge "eyes open" versus "eyes closed." And the viral loaner-car claim, for its part, remains unverified by any mainstream or primary source.
