Umm, I also found it to be a remarkably bad analogy.
More accurate would be something like:
"The chef instructor telks us every time we cook this flaming oil dish that can flame over unpredictably at any time so we should wear the welding helmet whenever possible. And I didn't bother and found it surprising."
Seriously, they tell us EVERY TIME ti wear seat belts at all times when seated. They don't do it just to annoy, confuse, or mislead the passengers. The only surprising thing to me is that such deaths are not more frequent. Despite efforts to predict turbulence, the forces at play when flying 600mph are insane in relation to the human body.
We need to respect that, because physics really DGAF about our opinions.
And thanks for insulting me when it seems to be an issue with your reading comprehension.
