My now deceased Father in Law used to ask people if they could cite the first rule of driving. After their incorrect guesses, his answer was, "Drive on the right side of the road."
In my younger years, being a wilderness guide and mountaineering instructor, I took my (then) new wife to the Sierra and set up a short rappel down a sheer cliff, making sure to set anchors for the belay and double stranded rappel ropes that an Ares rocket couldn't pull out. (Well, almost

) My wife enjoyed it greatly. When my FIL found out I'd taken her rappelling, he was livid.
I reassured him that I knew what I was doing and had set up an extremely conservative rappel, put a helmet on her, quadruple checked the harness, biners, rings, etc. and that it was very safe if the appropriate safety protocols were followed. He was not swayed.
I then said to him, "Tommie, you do something everyday that has far more potential to be deadly if just one single basic part of the rules is not followed."
"What on earth are you talking about?" he asked.
My answer, "As you so often imply Tommie, all you need to do is drive on the left side of the highway for a couple of seconds, and you'll be gone." To this, he could think of no reply.
(Note: this was in a time that was pre-air bags, pre-crumple zones, pre-telescoping steering columns, and in a place where seatbelt use was only a sometimes thing.)

We have created a world where much that we do is inherently dangerous. The danger has been mitigated for very many of those things through the establishment of safety protocols. Those who chose to ignore safety protocols, do so at their own peril. Those who adhere to those protocols usually go through life without incident.
Rhetorical question to any who doubt the need for safety protocols: Would YOU try standing up in the middle of modern roller coaster ride?
Use common sense; it's a valuable commodity!
