I have been driving home after midnight, coming from my where my parents live, a long distance away, and encountered a man who had climbed up into the elevated highway. It was straight and well-lit, but the best I could make out was that he was running at cars wielding a cardboard box (?). I began to decelerate and moved into the lane furthest from him, at the time, and after another car in front of me passed him, he moved into my lane. I'm still braking to slow down, and I change lanes to avoid him again, swerving and praying the lights in my rear view are slowing too and don't hit me as I try to avoid this man.

As I pass him, I manage to be one lane to his left, and he makes a lunge to try and jump in front of my vehicle. With some frequency, to this day I wonder how fucked I would have been if he succeeded in jumping in front of my car. The story I tell myself is that he was mentally unwell and thought he was heroically "tilting at windmills". It is more likely he was belligerently drunk, or was suicidal and wanted some help in it.

I don't know what makes something believable or unbelievable in your mind, but these are the details of an almost-incident that happened to me.
