    2:30 in the morning.

    No one in front of me for 1/2 mile on a 3 lane expressway.

    Cant see anyone in the rear view mirror.

    65MPH open road middle lane - NOA activated.


    Car wants to move to the left most lane. I figure - Strange but I let it.

    1/2 mile later...it wants to move back to the middle lane. What?


    It did this for over 6 miles as I thought it would stop. Nope...I had to move to cruse control ( NOA off ).


    It would surely be nice if Tesla could tell us why the cars do what they do.

    WAIT - did I just say that? Did I say that I want the car to explain itself to me? Have I accepted AI?

    Anyway...you get my point.

    I find NOA way to scary, and I've tried a few times but that's ok as it will improve.

    Other thing is that on my commute is HOV lane (580 SF Bay Area), I have use HOV disabled but NOA continually wants me to move into it. It signals, I abort it, couple miles/mins later it does it again, and repeats as long as I have it on.

    EDIT: I've tried to log bug on trip multiple times, but my Scottish accent usually ends up with 'Book Report: Up ahead large plane', or something along those lines !

    That seems odd. Basically, NOA does lane changes when the speed difference between you and the car in front exceeds a certain threshold (the threshold is set by your lane change setting). So for example, if you are going 80 mph and the car in front is only going 70 mph, the car will do lane changes more often. The idea is to change lanes to avoid traffic in front of you slowing you down. How fast were you going and what lane change setting you were on? Mad Max mode will do more lane changes. Did it look like the cars in front were going slower than you?

    Indeed … ODD is why I posted this in the first place.

    As I said. 65mph in the middle of 3 lanes.

    I have experienced just what you posted about NOA moving around to maintain current speeds in the best lane possible.

    As I said. The car in front of me was 1/2 mile away. It was just me and NOA on the open road.

    By any chance was it in an area where people would typically (when there is traffic) move to the left most lanes to avoid merging traffic? Mine does something similar in a local area (WB HWY18 at SR167, if anyone in Western WA reads this) where NoA prefers the left lane, even though right lane speed and traffic is fine.

    I don't understand the question.

    Cornfield on the right - Cornfield on the left.

    3 lanes in the middle and myself and NOA in the middle of those.

    No one else around for 1/2 mile.

    Not sure why the answer to your question would change anything since NOA is real time - live. Right?

    Does NOA make typical type adjustments now? I'm not sure if it does or not.

    Moderator note: thread title changed for clarity.

    Search the forums for “ping pong” and there are numerous threads using that phrase to describe Auto Steer moving the car side to side within a lane or the car moving inappropriately during an Automatic Lane Change. That is the common usage on TMC for the phrase “ping pong”, which is very different from what the OP described in this thread.

    Mine does this as well on a very specific stretch of the 15 FWY in San Diego. I just take it off NOA for a few miles.

    This happens on the NJ Turnpike in moderate traffic. Changes to left lane “to follow route “. Quickly changes back to middle or right lane without passing any vehicle. If I abort the left lane change it comes back almost immediately.
