I understand but I don't know that that's the main issue raised, at least it's not for me. It's more a matter of wanting to understand what happened which, I think, is natural.
This wasn't a simple to understand crash like those seen with inexperienced young drivers, or on high-speed crowded roads or on notoriously dangerous curvy mountain roads or in weather with poor visibility or as a result of "drag racing" or so far as we know, due to alcohol (esp after not looking drunk 20 min before) or any other "not really surprising" crash we hear about. It was reported Anne also came close to hitting a pedestrian, did hit a Jaguar, hit the apartment building and then hit the home. That speaks to some sort of unusual impairment (to me.) And Anne did have a history of some mental health issues. Perhaps suggesting there could be a mental health cause for the accident creates stigma. I wouldn't think so-- to me it's no different from suspecting a blood sugar problem if someone faints if we know the person has a history of diabetes. Both look to a known history for clues. And reckless behavior may be seen with mania and one DSM criterion can include that:
"Excessive involvement in activities that have a high potential for painful consequences (e.g., engaging in unrestrained buying sprees, sexual indiscretions, or foolish business investments)"
I don't know that mania was likely. But I do wonder what went on on Wed and Thurs before the crash.
