FSD attempted a very bad lane change - into an occupied lane. The other car swerved, and I intervened, so no crash. Barely.
Entering the MacArthur Maze in Oakland, coming onto I80 E from Jackson St. Routing is to the next exit onto hwy 24, which is very close, so we should stay in the lane we entered on. But FSD blinked and immediately started a lane change to the left. But there was a car right there. He swerved, I yanked back into our lane, no damage done.
Here we are, in the proper lane, but FSD is already crossing into the lane to our left. Yes, the left repeater cam show the car we are about to crash into.

Here is that left side repeater cam view, and you can see that we are already over the lane line, and that the other car has already started to swerve to avoid us. This is about the time I disengaged by steering back into our land.

This is the worst, and clearly unsafe move I have seen from FSD. Yet.
Both the other driver and I acted to prevent a collision. But it underscores that FSD is fully capable of bad and dangerous mistakes.
My guess is that the car was switching from V12 to V11 Highway Code. But it was a very bad screwup. I think someone else reported a similar very improper lane change a few days ago. And, yes, I made a verbal report and snagged trigged the dash cam so I could share these photos.
By the way, this is why I use the Minimal Lane Changes setting, unless I forget to set it at the start of every drive. In the default mode, FSD makes lane changes unexpectedly, so it is not possible to anticipate and check for clearance in advance. This setting should persist between drives.
