I discovered LKAS today. I knew that if I wandered too close to the edge of the road the car would try to turn the wheels away from the edges of the road, (even if there is no white line by the way). I didn't realise until I saw a video of someone trying it that the car will drive itself. I had the car in cruise control, my hands were lightly holding the wheel, the car was making the bends in the road by itself. If I took my hands off the wheel a red warning popped up. It seems the steering wheel needs a small nudge from the driver every few seconds. I don't imagine I'll be using self-drive but it's an interesting novelty.
