I’ve been on a road trip in my 2023 Model S (HW4). I’ve used FSD for almost all of my driving, both on and off the highway. I started the trip with 2024.3.25, then updated to 2024.14.9 during the trip. Both versions have FSD v12.3.6. I know that on the highway, the car uses FSD v11.
One annoying issue that occurred frequently throughout the trip: when I initiated a lane change using the turn signal button, the car would not change lanes. The turn signal would come on, but the blue line showing the car’s path didn’t curve into the target lane, and I had to eventually disengage FSD to change lanes. This happened mostly on the highway, and most often when changing lanes to the right. It seemed to happen more when there were no cars ahead of me, but it did happen with more traffic too. In some cases it seemed I could force the lane change by turning the wheel slightly (without disengaging), but not always. I would estimate that this happened with 40% of my lane changes to the right, and was responsible for 95% of my FSD disengagements. I reported the issue many times using the voice recording that you get prompted for, but I stopped doing that after a while.
I did a road trip in the same car last fall, using FSD v11 (I don’t remember which specific version). Auto lane changes sometimes failed with that version too, but not nearly as often as with the current version. In most other respects, FSD v12.3.6 was far better than the previous version, and I was able to use it pretty much everywhere. The only places I didn’t use it was in residential communities with narrow roads and low speed limits, because the auto speed offset feature would allow the car to go too fast.
