Just out of curiosity and for comparative purposes...
You named about 5 anomalies that weighed your decision not to wear belts. How many instances did you see where a seat belt probably saved the life of the person involved in an accident?
In all honesty, that is difficult to answer. Of course, I have seen accidents where there were survivors. But the reasons for their survival were not known to me. Were they wearing seat belts? I don't know. Maybe. As a long haul trucker, the majority of the accidents I saw were of the type that seat belts wouldn't have mattered either way. The images that stuck in my mind were the horrific ones where the victim might have survived if it were not for a seat belt malfunction or if there had been more freedom of movement. Or, in the odd case where the seat belt itself caused injury.
In my own case, I was going through an intersection across a four lane highway. I had the green light and had just started across when I saw a pickup coming at me from the left at a pretty good clip and that he was going to run the red light. I knew I didn't have a chance of getting out of his way and all I knew to do was to dive for the passenger's side. A half second later, the driver's side of my vehicle was completely demolished. My vehicle was pushed off the road, into a ditch. I managed to crawl out of the passenger side and get away from the wreck. The impact caused massive subcutaneous hematoma (sp?) in my left leg and I was off my feet for three months as the blood vessels in my leg rerouted and healed. I still have trouble with that leg. The other driver was killed. I don't know if he was wearing a seat belt or not. I never asked. But if I'd been wearing a seat belt, I would have been smashed right there in the driver's seat.
Have there been accidents I've witnessed where seat belts saved lives. Probably. They just aren't the ones that burned themselves into my memory.
The two road accidents that have had the greatest effect on me, I think, involved trapped victims in burning vehicles. The first happened on a narrow, two-lane road in Southern West Virginia. I was hauling mine timbers to a mine in Raleigh County and I was taking my time and being as careful as possible on a bad road. A little red two-door sedan had been riding my six for several miles and it was obvious she wanted around me. She suddenly shot around me, passing me on a curve, and was out of sight in seconds. A few minutes later, I found her car lying on its side in somebody's front yard. Several other motorists and another trucker had pulled over to help and I pulled my rig off the road and got out.
The woman in the car was unconscious. Her windows were up and her doors were locked. Smoke was coming from the engine compartment. Somebody broke a window and climbed into the car. They couldn't get the seat belt unbuckled. The car suddenly caught fire and the rescuers were forced to back away. The other trucker and I grabbed our fire extinguishers but the fire was too intense. We couldn't put it out. We could smell burning flesh mixed with the smells of burning oil and gasoline. Thankfully, the woman never regained consciousness.
The second was down in North Carolina coming off Fancy Gap. A a south bound fuel tanker's brakes overheated and failed. Two North Carolina Troopers were running ahead of the rig, trying to clear the way. At the bottom of the mountain, the driver lost control and jack-knifed. The tanker ruptured and spilled fuel onto the cab. The fuel ignited. The driver tried to get out, but he couldn't get his seat belt undone. Whether it was a mechanical malfunction or his own state of panic, I don't know. When the fire took him, he was screaming for the Troopers to shoot him. Of course, they couldn't. Legally, that would have been murder.
I have been unfortunate enough to have witnessed several deaths by fire, the first when I was only four. The house next door to ours caught fire and three small children died. And, as previously mentioned, one of my old flight instructors. Back when I was a kid, I had a part time job at a horse stable. One night, there was a fire and the horses all died. The authorities later learned that the stable's owner had set the fire to collect the insurance. The horses weren't human, but they screamed as they died. I'm not frightened by many things, but death by fire is right there at the top of the list. I decided years ago that I would rather take my chances without a seat belt and rely on my skill as a driver, situational awareness and defensive driving. It's worked so far, knock on wood.
Does this mean that I advise others to do the same. Absolutely not. It just happens to be my choice, my way of dealing with my own demons.
This is too depressing. If I were a drinking man, I'd go tie one on. But I'm not, so I'll just leave things as they are and try to get some sleep.
