I would freak out like that guy, FSD would not comprehend a pit (pothole category?), I don't think?
Actually with my FSD beta the car often sees potholes, but doesn’t visualize them, and swerved to avoid them thinking they are large potholes.
Likewise when there’s a large fresh squeezed patch of asphalt in the road the car often gets confused that it’s a massive dark hole and try’s to panic stop before it realizes it’s not.
