When I was a young man I drove tractor trailer for eight years. One rainy night I was running with two friends on a four lane highway in central Minnesota. I was number three in a three truck convoy, although we were space probably a hundred yards apart. It was one in the morning when two young women passed me in the rain and pulled in behind the truck in front of me. Then they pulled out and passed him pulling in in front of him. I didn't actually see what happened next, but learned later that they pulled out and passed the lead semi but when they pulled back in they caught his left bumper turning the car sideways and both trucks in front of me ran over the car. I got stopped.
They both died. Their car was crushed down to truck bumper level. I could never figure out why on a four lane highway they kept pulling out to pass and then pulling back in line. They could have just stayed in the left lane.
They were two young school teachers who had been playing Bingo in a nearby town on their way home.
We used to see a lot of accidents in those days, back in the sixties, but due to better highways not so many these days.
Something like that really sobers you up. No, no, I don't mean from drinking.
