Oh no, I am not saying it was her fault... or that the answer would be more comforting. I am just wondering if there was some kind of, say, drug/alcohol use, combined with domestic abuse, an argument, etc and she got out of the car and passed out. Something more complicated than her walking alone and getting assaulted by a stranger... which is usually more rare than domestic abuse by a known person, especially if substances are involved. Again, not that it is any less terrible (certainly not), but those are the kinds of situations that most women *don't* know how to protect themselves against... being abused by someone familiar.
Personally, I found it extremely helpful to take a self-defense course as well as always keeping my ears and eyes aware when walking anywhere, day or night (no headphones, ever), and having a posture & pace of walking that says "don't fuck with me." And to not get intoxicated with people I don't trust (I made a very bad mistake of that, once.) Not that any of these things are guaranteed, but at least I feel more confident because of it.
