FSD error on tight hairpin paved roads

[ddmitch1]

My brand new July 2025 CT made an error driving with FSD on a paved road with a 10 mph hairpin ~150 degree corner. FSD turned too sharply, crossing over double yellow lines, ending up on the wrong side of those double yellow line markings, and stayed there for over 100' until I steered it back. I could have corrected this quickly but I wanted to see if FSD would correct itself on this low use road. I had a 2024 CT that did the same thing in FSD on another paved mountain road with double yellow lines on a tight hairpin corner . This needs to be corrected before FSD gets unsupervised. I was surprised FSD did not correct itself from being on the wrong side of double yellow lines in both cases. In both cases there were no other cars nearby so I was able to see if FSD would get back on the correct side of the road. It did not and seemed happy to continue on the wrong side of the road.

I’ve had that happen as well - I didn’t give it much time to see if it would correct but same.
