This sounds very much like my car -- mine is new (less than 2,000 mi) so I wasn't sure if this resulted from the V10 update (it never happened prior to the update) or just a wiring/computer glitch that I hadn't noticed before. Mine has swerved this way on all types of roads including 2-lane roads (going across the center line) and multilane highways and has swerved toward cars in adjacent lanes. It definitely is a major safety issue and makes autopilot unusable. When it happens, the screen animation shows my car crossing the lane markers so it doesn't appear to be a camera/sensor issue.

AP zig zag down road

No, I think this new behavior represents a big shift from literal processing to AI in lane keeping. We are seeing responses from the surroundings, not just lane lines. While I do prefer the stability that V 9 had, I also think that to move forward, they had to make this change. It does seem like a step backwards, but I've done enough software development to know that big enhancements do come with their preliminary bu... uh, "features."

You'll see my posts in this thread about how much I disliked the V10 behavior - and was embarrassed to have any passengers experience the wonkieness of EAP...
However! I got 32.11.1 on Thursday, and used EAP much of the weekend - and I have to say that not only is the 'lane hunting' and 'jerkiness' now totally gone... I am, again, proud to show passengers how awesome EAP is! THIS is why I love Tesla. Every now and again, we'll feel like we went 'backwards'... but it's only temporary, and a much improved version is just around the corner.
I still feel the car veer away from large vehicles... which is nice. But it's not jerking the steering wheel as I approach, and as I pass the large vehicle. It's noticeable... but not at all uncomfortable.
So far, in my experience, this is the most stable EAP yet!

Man, that's unreal. It's as if your Tesla downloaded the wrong software, like it came from a 737-Max or something. I'd be waiting at the service center next day when their doors opened.
So yeah, it is because the update. As other people stated here you can also see the behavior in the display. If you have FSD and you go on “navigate with AP” you can see the blue line that the car draws in the display also doing zig zas
Indeed. I am a software developer with some years of experience too and working also with ML/AI and this can be just a data collection from all the cars and a model training for the software. It makes sense and that can explain why the car sometimes does it and sometimes not. They need to collect a lot of data in order to train well the models that the car uses internally. Lets hope they collect as much as they can and they launch an update
I finally got it in for service -- they said that the autopilot just needed to be re-calibrated. But on my drive home from the service center (2.5 hrs) it was even worse and on top of that they forgot to replace my USB memory stick so I couldn't record videos of the wild swerving across lanes on autopilot. I've tried texting and emailing the service center but no reply...
Experiencing the same thing. I just updated to v10 (I am on standard AP) yesterday and have driven over 7k miles since pick-up back in June 2019. I would say over 85% have been on auto pilot and never had the zig zagging inside the lane on a completely open freeway with well marked lines.
Double yellow lines seem to bounce between single and double which I guess changes the lane width and maybe the car corrects. This happens on all lanes though. Had an incident while I was sitting in stop and go traffic where the carpool lane entrance had no lines. The car freaked out after sitting for about 30 seconds. It threw the big red steering wheel image, put the car in park, and turned on the hazards on its own.
The new version is reacting to conditions in more bad ways than good for me. I guess I will have to learn how this version of autopilot reacts to the daily commute. For the most part though, stop and go traffic is good. Zig zag is too much so I’ll probably be using TACC until it’s resolved. I’m pretty bummed out though. On the freeway, pretty much the only time I’m not on auto pilot is when I change lanes(non FSD). Can Tesla roll software back to a previous version?
Tesla just opened a new service center down the street from me, I’ll have to stop by and have them take a look.

Got the update as well! Much better improvement over the last versions it feels like so far. It definitely reacts to semi trucks now unlike before then move back to center after passing. The maneuver feels confident and has no issues finding center after. Wasn’t windy today so can’t say how it reacts to a semi drifting into the lane though. Normally have to take over but I’m curious to see.
Side note this update also fixed the compass issue I got with the update where the map would constantly spin almost 180* and then back.

Its in Beta form which is just like Apple programmes in Beta. Things will go wrong and up to you to log these faults with Tesla. You have to be fully awake with both eyes on the road to take over at anytime otherwise don't use it and wait for Tesla's full release just like Apple does with its hardware programmes.
