Hola, regarding unexplainable and one of a kind occurrences, I was driving the same old Vw Van near Guaymas. It was about 3 am and I was sleepy. My wife and offspring were asleep in the bed in back.
I noticed big lights coming towards me in what appeared to be in my lane, being sleepy, I assumed that the road curved to the right and so gave an illusion, so I happily continued driving.
When it was about 50 yards away I suddenly woke up ad realized that It was a semi and it WAS in my lane. To the right, the road dropped off about 10 ft with a 50-6o degree slope. there was only about 4 ft of level ground between the hiway and the drop off. They had small concrete posts set about 1/2 way betwen the road and the dropoff.
So I had a probelm, should I go as far to the Right as possible, to try for a a partial head on collision and risk a roll over, or to the left and chance a head on collision? The choice wasn't difficult, to the right.
So I went as far as I dared, expecting to roll over, the font bumper was hitting the concrete posts, this woke my family. I couldn't go one inch more but the lights and that huge wheel was still directly in line with "me".
I had no choice but to just keep on going as I was since it gave them the only chance to survive, I assmed that I would take the impact directly personally, and so wrote myself off.
When the truck was perhaps 20 ft away I knew that I would never survive the impact, since it was still directly in line with me, when it suddenly shifted to the left, no, it did "not swerve", just jumped to the left enough to clear the van. I continued on trying to get bk unto the pavement meanwhile watching the truck's lights in my rear vison mirror, then the truck's brake lights came on and it swerved violently to he right into it's own lane. I realized that the driver had suddenly awakened and had tried to take evasive action but too late. I flashed my lights at him so he realized that I was alright, so he drove off. There was a small restaurant and parking area about 2 miles down the road, so I parked there to see what damage had been done to the VAn.
The next morning I found no damage to the VAN, but the front bumper showed the impacts directly in the middle.
I then drove back to the spot to see just what had happed, and was stumped! I still am. I found his skid marks where he had belatedly tried to stop, they were almost completely inside of my lane, there was no way that he could have avoided hitting me

??
I then looked at the concrete posts that I had hit, from this point to the edge of the drop off was only 2 feet. In other words, my right wheels had been suspended in the air?
K Gentlemen, Gals explanation??
This is to me a classical example of a one of a kind, non-repeatable occurrence. How would science explain it?
