As an example I once got in a car with people I'd just met. After driving a few blocks one of them held a gun to my head. The driver then drove us out to the middle of nowhere... I was convinced I was going to be killed. I couldn't say how long the drive was but it felt like hours. They "just" robbed me and left me there. Frankly, dealing with the police after this was just as traumatizing as the initial experience - after I described the perpetrators (yes, including race) and the overall situation they assumed it was a drug deal gone bad (even though I've never had anything to do with drugs) and more or less dismissed me. They actually took it a step further and started mocking me. Essentially, they heard the race of the suspects and assumed I was initially in that situation because of something criminal (I'm white). It was awful.
I was pretty traumatized for a while but in the years since I'm much more aware of my surroundings at all times. I certainly don't trust people I don't know well and put myself in situations even remotely similar to that. I definitely have some PTSD but it doesn't impact my life much on a daily basis. In telling this story people frequently respond with "that was stupid". I can't say I disagree but it's also been eye-opening to observe a lot of casual and overt racism in response.
Point being, I essentially "victim blame" myself to some extent. I don't know if that's psychologically good or bad but what I do know is factoring everything in the chances of anything like that ever happening to me again are much lower. I'm not an outdoors type person but I imagine that (as the article describes) similar factors can easily and rapidly assemble to lead to more-or-less near death experiences.
