Tesla Autopilot was on in I-35 crash that killed its driver

Reads much like it was LLM-written, but the facts seem to indicate it was a single-vehicle crash at 73mph in a 70mph zone where the vehicle veered off the highway in to a guardrail. The sole occupant was wearing a seat belt at the time of the accident. I was expecting speeding or some other kind of reckless behavior, but none was evident from what I could tell. It's sad that this was fatal.

Keep your hands on the wheel, y'all. :-(

Redactions should be disallowed when a human death is involved.

Can someone please tell me what the passenger was doing while the autopilot drove the car ?
