I’ve been driving my id4 for about a month now and while LKA does well in between dashed or solid white lines, it doesn’t seem to do well with the solid yellow of the inner lane. Instead, it seems to want to use the k-wall which can be a little too close then there’s not a shoulder. Has anyone else experienced this? Similar issue with double white lines that denote the carpool lane. I wonder if it can be improved upon.
Thanks

I would agree. Also sometimes the lane is marked yellow on the screen so I thought it recognizes the actual yellow lane but then it goes back to green or white again

A yellow lane on screen means your driving too close to the line. No correlation to the actual color of the road marki.

I drove through construction hell west of Houston yesterday. It was so confused that I wished that I could disable it f of r a while.

Oh thanks for the explanation. Us that in the manual? Poor color choice in that case. Maybe good for europe who has no yellow lanes. Red would work better then I guess.

Ok i tried again on the hwy. Travel assist was active. Green lines on display. I pull slowly to the left lane. Green lanes disappear but the left line never got yellow or red. Then I did approach the yellow line on the left. Nothing happens never got yellow line. Basically i have no idea what the yellow line means but it seems it has nothing to do with me approaching the lane

Just yesterday I was on one of our County roads, marked with a solid yellow center line, and the LKA worked just fine as I approached too close when yielding more curb space to a pedestrian. I then reminded myself to use my directional signal when doing so.

I think more accurately the display turns yellow when lane keep assist actively engages to pull you back into the lane.

On a related note I got to experience what the car does when you try to change lanes when it thinks a car is next to you. Blinker on, the light on the side mirror is blinking rapidly but the car was back enough that I could fit. When you try to change lanes the car very aggressively tries to keep you in your lane. I had to apply a lot of force on the steering wheel to get over to the other lane. Pretty cool feature that I can see being useful when not fully paying attention or fail to see a car in your blind spot.

I have never noticed any difference with what the car does with different color lines on the road.

I have found that Travel Assist doesn't like shadows unless you are in constant shadow or constant sunlight. I drive on a two lane road frequently that is lined on both sides by tall mostly pine trees. In the mornings it is the east side trees that cast a shadow across the road and the west side trees in late afternoons. If I am driving into only a couple of shadows on a sunny day no problem, the car handles it well. If it is an area where there is a constant in/out section of shadow and direct sun the Travel Assist loses it's mind. You might call this an area of strobe effect or maybe picket fencing. Travel Assist just can't handle it. This is a constant thing, not a one time glitch. I just don't use Travel Assist when in this situation.

Yes, I’ve noticed this as well with the shadows from power lines parallel to the road. At just the right time the shadow runs near the edge of the road and the “catenary” curve of the shadow will sometimes engage LKA.
