Adjusting Lane Keeping Assist
I know it's a collision avoidance item but at times I wonder if it's really a safety item. I tend to drive close to the right edge of the road so the lane keeping interjects rather frequently. My V90 would allow you to have the jerking of the steering wheel, or vibration of the steering wheel, or OFF. I looked in the owners manual and it says you can set the system to "Early, Med, or Late". I just want to turn off the jerking of the steering wheel, which I find dangerous, and stick with vibration only. Any idea how to do that? And what is Early vs Med vs Late ??

Don't want to deactivate. I make several 5+ hour drives per year and the lane assist is kind of reassuring. Could have used it on a previously owned Cadillac which didn't have the feature when I started to doze off and left the road--fortunately with a wide, smooth shoulder.
I find the steering jerk is much too aggressive. Lately I don't even feel the vibration before the wheel is twisted.

Sounds like you want a warning (alert) and not a correction (assist). My W204 is just a warning, so I understand the preference.
Thinking out loud here: I appreciate this sounds like the opposite of what you are asking, but if you want the assist ON, but don't enjoy the violence of the correction, maybe setting it to "Early" would minimize the magnitude of the steering correction or magnitude of the steering wheel jerking, but maintain the outright safety for the moments when attention slipped and going off road would be very bad.

I do have to wonder: If you have steering assist and lane assist activated and the right side lane marker disappears, like at a crossroads, would the car steer to the right (my V90 would) and then after the intersection when the marker reappears, think you're going off the road and activate the correction, which the steering assist will try to correct, setting up a pingpong situation....

Since I don't know what the Early/Med/Late actually mean (and the owner's manual is useless) I've decided to drive a bit in the Early and Late mode (it has been set at Med) and see what happens. If I come to any conclusions I'll let all y'all know....

Regarding your initial post. If you are driving so close to the right or left edge to engage the active lane keep assist, then your driving technique is the problem, not the car. You should be centered in the lane or at least not be hugging the line. It's dangerous driving that way. We all have to steer around obstacles in the road and will occasionally need to move right or left to avoid them and possibly cause the lane keep assist to react. If it does, then having a firm hold of the wheel usually works and in extreme circumstances use a blinker to disable the system for a moment.

I recall driving on US 6 that was 18' wide with curbs through Iowa back in the day. The speed limit was "reasonable and proper", typically 85-90 mph, before speed was reduced to 70 mph IIRC around 1959. One was always driving close to the edge in more ways than one.

To have active steering assist, you have to be using cruise control. I've gone through intersections in rural and country roads with cruise control set at 55mph and had no issues with active steering assist. You go through so fast it's all but a second where there is no line. Going through an intersection at slow speeds may be more of an issue, but I would question why you would have cruise control on in that situation. In either case, in an intersection with no lines on either side the car will disable active lane keep assist and therefore make no correction at all. I see this all the time on country roads where the lines are faded or, in some cases, don't exist. The steering wheel icon turns gray in that case and will not course correct.

I developed the "keeping right" driving tehnique. after moving to Maine where: 90 % of my driving is on not overly wide rural roads; overloaded logging trucks think they own both lanes; from November through March every pick-up has a snow plow mounted to their front which extend about a foot either side of the vehicle (and from May through September they're towing large boat trailers or landscaping equipment); and a majority of car accidents are head-on because a driver crossed the center line. I used to joke that every Maine driver must have flunked coloring in kindergarten because they couldn't stay inside the lines......

Have been fiddling with the "early-medium-late" strings for lane keeping. Found Early to be pretty close to Medium. But Late is really late. Deliberately crossed over the right hand white line and hardly noticed any intervention. Still don't understand the logic. Sometime I got the jerking of the wheel, sometimes the vibration. Did prefer the Late setting, though, and I'll keep it there, at least for awhile
