If you slowly approach a lane line, the LKA will give the steering a little nudge (you can feel it) and the green car light on the dashboard will come on, indicating that you were close to the line and that it has been corrected for you. If the light comes on too much, it means that you are not used to the size of the car and you are too close to a line. It’s a lot wider than a car or normal car, so it takes some getting used to. Around town, the boosts feel smoother, but as you get up to freeway speeds, they can make the steering wheel shudder, and I could see how this movement could bother motion-sensitive people.
If you approach a line too quickly, you get Lane Departure Warning, which is yellow lights flashing on the HUD and the lane line flashing on the dashboard.
Yes, use the steering wheel button (bottom right) to turn off Lane Keeping Assist (LKA). Sometimes I have to do this when the AZ sun reflects off the road at a certain angle and it looks like there are more lane lines than there are.
But as you get used to the car, you will rarely find LKA ignition.
