I've watched that a couple times and I'm pretty sure he accidentally cancelled autopilot by jerking the wheel with his hands. His hand movement lines up with the autopilot disengage. I've done that several times myself, it is deliberately sensitive to wheel torque as a manual disengagement mechanism.
the footage he posted on x does not fully match the in car footage on youtube so there was evidently multiple runs. it seems unlikely that the mirror wall could be repaired so I am left to conclude that he kept driving the tesla at the wall until he crashed through it (manually). that being said I would not be super surprised to find that a carefully crafted mirror wall would confuse autopilot. that seems to be a logical weakness of a vision based system.
