No, that's not what it's doing. Lane Assist, doesn't help you by tugging the wheel and altering you. It actually reduces Fatigue by doing some of the fine adjustments for you.
How many times have you tried to "wake yourself" by turning up the radio, turning up AC or whatever. It might help, but it doesn't last long at all. If you are tired, your tired and there isn't much you can do about it (except maybe drugs
The "Lane Assist" reduces how fast you get tired from driving.
I tried it on my wife last night. And she was pretty tired and it was late but she made the whole trip fine. In fact, she said she was more tired when she started than when she finish the 120 mile trip !!
Just for clarity, reduced fatigue not what the opening post or this thread was about. I was also concerned the ADDITIONAL feature of this system, "Lane Departure Warning" was working as design or not. "Departure Warning" is to help notify you, you are too impaired to drive. Which doesn't really work very well under 60 MPH. It might only delay the inevitable a few moments. A niggle in the wheel or an icon on the screen changing green to yellow is not gonna sway a driver that is impaired. Because it changes to yellow and niggles the wheel all the time. The put your hands on the wheel alarm might get your attention. But it's not like the Crash Warning BRAKE warning. More like the "FOB left the car warning", pretty mild.
Also if your hands are on the wheel it will never set off any "alarm".
