This is incorrect. My 2018 SL has the Intelligent Driver Alertness system, which has warned me on a few occasions after I've spaced out during a drive.
"How does it work?
Using steering angle sensors, DAA monitors steering input patterns to establish a baseline or a “snapshot” of how you were driving. Then, it continuously compares subsequent driving patterns to the most recent snapshot using a statistical analysis of steering corrections."
This just detects bad steering inputs, and if you are already using steering assist it will do just about nothing. I'm talking about systems that actually monitor your eyes.
