Faiaoga, this is actually a real event that took place about 9AM on a Saturday morning in January of 1991. My daughter and I were on the way to a Toyota dealer in Frederick Maryland to buy her a car for college. The accident happened as it was described, and I don't like to think of what may have happened if I had not had a knife handy. I wrote it as a short story for reasons of modesty. It was one time in my life that a sharp knife was needed right then, not in a while. I doubt the woman would have been burned to death, but asphyxiation was the problem. The smoke from the burning engine grease was a black sticky smoke that was worse then tear gas for closing the throat up. As it was, it took two Cokes and two sticks of gum to clear my throat of the taste and stink of it. Would the gas have went up? I don't know. There was plenty of it spilling out, and I know that I was scared silly crawling back into the wreck to get the dumb broad out.
Everyone should have some kind of shape little knife right on the keyring, so it can be accessed if need be by the driver in an over turned car. Since that day, my daughter has been a fanatic on keeping a knife right on her car keys. Any kind of small sharp blade will slice through seat belt webbing, even a Victorinox classic.
Carl.
