I experience this too, usually in the left highway lane, and I wonder if it has to do with the rumble stripping or a solid or yellow line. I do like the feature, and feel good about what the car would do if I had a medical event and lost consciousness. But I don't take my hands off the wheel near other cars. When I let TA choose the positioning, I usually see the cars in my mirrors adjust to give me more room... still, it's better than using your knees or other practices when attempting frowned-upon acts, such as blowing your nose or opening a water bottle.

 

That’s actually one of my favorite features in TravelAssist. You have the ability to set it to keep to one side of the lane or the other by just turning the wheel slightly. It will remember that and stay toward that side of the lane. My Tesla owning friend is jealous of that as his car likes to get uncomfortably close to barriers in construction zones and if he moves it, it shuts off!

 

+1 on this, favorite thing about it is it lets you set it up where you want in the lane. If you don't like where it's centering, it's probably because you set it up while left or right biased thinking it would move itself over to the center. You can change where it is in the lane by manually moving over (without turning the lane centering off). It will change to "centering" on the new position after about 3 seconds. Love it

 

Thank you so much! I will give this a try.

 

wanted to share this experience. months ago, my ADAS lane keep leans towards the right side of the lane every so often... like for a mile driven it does it then corrects itself-ish, then happens again. shortly after the drive, I decided to check my tire pressure and discovered my rear right side was under inflated by 3psi vs other 3. just saying cuz i'm not 100% certain this is related. I've not had that issue ever since I inflated that tire properly to match other 3. btw, this was with our MY22 ProAWD traveling 70mph on Central Cali's 5 interstate freeway going north.

 

Sounds reasonable. The imbalance would cause a subtle pull to one side, and the sensors wouldn't differentiate between that or your steering. Of course this is just an opinion from a non-engineer.

 

I tried Travel assist on highway today & it worked well.
While travel assist is on I wanted to change lane. So I put a left blinker on and it went way way left & I had to control. Other time when I did left blinker it tried to go right.
so opened travel assist & notice lane change assist is off. So I turned it on.
After that the lane change worked.. so I am thinking this is culprit..

 

I honestly did not know you could manually adapt where in the lane it chooses, that is really neat to say the least. Going to try this one day.

One side note about TA. The shiny asphalt crack seal they use makes it go bananas in certain angles of sunlight, have experienced it twice now only during a specific commute window on a limited access highway that has a lot of crack sealing, the steering wheel twitches like crazy. TA still works to keep centered but you just gotta hang onto the wheel the entire time.

 

Demonstration here on "manually" adjusting where in the lane

Yes lines that look like road markers are going to be a challenge for a visual only system. GM SuperCruise and others use GPS but then you only have it where mapped...
