"take a break" - the feature prompts the driver to “take a break” with that text and a‘coffee cup” logo after a certain period of continuous driving. There are instances when turning it off is necessary and Hyundai has removed that option - high distracting false alarm rate. The alert, visual and auditory are intrusive, unnecessary, demonstrate a high false alarm rate leading to frustration and distraction. While designed as a safety feature, it has the opposite effect. The system inaccurately interprets the driver’s behavior as signs of fatigue with alerts popping up at an alarming rate. Perfectly normal and safe driving behaviors see the alert popping up again and again. Further there are environmental interferences - bright sunlight, reflections off glasses, bumpy roads requiring frequent corrections - system interprets these as driver inattention and cannot tell the difference between drowsy driving and navigating a poorly maintained highway. New Hyundai models do not allow the driver to disable the take a break alert. “you’re cruising down the highway, minding your own business, alert and focused, when your Hyundai flashes a coffee cup icon and tells you to take a break. Again - this for the third or fourth time in 20 minutes. You’re not tired, not swerving, and frankly, you’re getting annoyed”. The system is disruptive and unsafe as it disrupts the driver activating when the system detects inattentive driving, suggesting breaks even if the driver does not feel fatigued. The alert can illuminate even during short drives of less than 30 minutes. The alert can occur extremely frequently, especially during long drives, which is extremely annoying. The warning can appear shortly after starting a trip and may repeat every few minutes, which is extremely frustrating. It is far more disruptive than safe and helpful.
I engaged the adaptive cruise control at 50 mph. This enabled the driver attention system which I had turned off at the start of my drive. The driver attention system is unable to see my eyes through my prescription corrective lenses. This caused the Hyundai to throw multiple 'failure to control vehicle/failure to watch road' warnings over the course of a few seconds; culminating with the system trying to stop the car in heavy traffic.
