Go watch the youtube video of another Tesla owner testing the intersection where this accident occurred. The lane markers on the left side vanish but there is a divider marker setup. It's super clear the Tesla followed the divider marker thinking it was a lane and hit the jersey barrier.
Also of note the impact attenuator was completely missing due to bad highway maintenance. If the tesla had struck an engineered set of barrels instead of side striking a jersey barrier the driver would have walked away.
I've seen it, and it has zero effect on what I said. The car "thinking it's in a lane" while being misaligned? I can possibly blame the people that draw lane markings. The car "thinking it's in a lane" while it slams into/past the edge of the road? 100% the car's fault. It shouldn't do that even if there are no lane markings at all.
