I don't really feel that strongly about seatbelts, other than the fact that those not wearing them typically engage in other high risk behaviors.
Look, my husband has survived accidents drunk (one with a semi) due to not wearing a seatbelt. I understand that all things can happen, but frankly, if you aren't wearing a seatbelt you are more likely to HAVE that kind of nuts accident that saves your life BECAUSE you weren't wearing one. Also, if my husband had not routinely driven drunk and seatbeltless, he would have had FAR LESS of the kind of catastrophic injuries than he wound up with DUE TO THE REST of the high risk behavior. And "living through" that type of accident is not as fun as it sounds. I don't believe he enjoyed climbing out of the truck that crushed around him (his ability to curl into a ball saved him, hence the "seatbeltless" GOOD, only it's not really that great to HAVE such an accident at all. He did not enjoy his year plus stay in the hospital while learning how to walk, poop, eat, and also get weaned off opiates.
My point was more, the type of person who thinks "I don't need a seatbelt" is OFTEN the cause of their own salvation, BECAUSE they get into those types of situations that result in the kind of freak accident where someone winds up in a tree.
Watching him age is really an exercise in gratitude that I don't have any major PHYSICAL stuff going on. Also, he wears his seatbelt now. He got into another car accident, sober, and broke his neck again (not by his own cause, it was the other driver's fault). And YET, his lack of concern for himself and others came back to bite him. You break your neck once, you are FAR more likely to break it again, as it's more fragile. It was a "walk away" type accident for most people.. Not him.
So, there are consequences to risky behavior, and it often goes hand in hand with risk takers.
The fact remains, seatbelts are used because overall (whether living or dying) they reduce injury and death. Those kind of "oh my, so GOOD that person was not wearing a seatbelt" accidents are not the norm, and when they occur, it's luck, providence, fate, whatever you want.
I merely point out that seatbelt use does not occur in a vacuum, it is an overall societal good.
I feel the same way about vaping, but I don't think the seatbelt analogy really matters so very much indeed. It's really not a good analogy (at all, for either side) to use for vaping.
