There's so many indicators that FSD is ages away from being safe, and so many stories of Tesla's just randomly steering in towards barriers and needing quick action from their drivers, even as recent as last month.
Here's a video from a few days ago of Tesla's Autopilot seemingly getting confused by a line made out of dirt, veering off-road and crashing[1].
Also was there a mention of the car following the dirt line? It seems to me it loses traction way before that, and most likely disengages.

Also, I believe off-ramp functionality was only added recently with 'navigate on autopilot', if someone tried this without taking over as instructed, well...
