That's not very indictive of Tesla. The driver ignored multiple signs posted with a 25mph limit, yellow 'tight curve ahead' signs and all, with plenty of time to spare.
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.
Who was driving? Autopilot or "the person in the driver’s seat [who] is only there for legal reasons. He is not doing anything. The car is driving itself."[1]?
That's a red herring, full self driving is not enabled in any car and drivers are fully aware. I failed to find any more information on this video. The dashboard is not visible, there is no sound, no way to tell if Autopilot was engaged or not, or if the car is even a Tesla.
Also, I believe off-ramp functionality was only added recently with 'navigate on autopilot', if someone tried this without taking over as instructed, well...
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].
