Unfortunately, not everyone is as smart/sensible as you are, plus there are people who may be new to a community and just don't know. In the old days, they'd talk about greenhorns who'd get lost on the prairies during blizzards because they didn't know the tips and tricks for how to navigate when there were no trees or other landmarks. As time passed, those tips and tricks evolved into modern day admonitions for how not to freeze to death if your car got stuck, etc. Things that you don't perhaps ever think of because it was something you learned over time. Same thing with people who don't consider their hydration when going camping or hiking in Big Bend or any safety precaution that someone raised in the hotter climes would seemingly 'just know.'
Since I'd been raised in a climate where winter temps dropped below freezing, there was often snow, and the area had actual 'seasons,' I figured I knew the score. Then we moved way up north and it was a different scene. My coat was not warm enough for days when the high was a negative number. When I had to crawl into the car from the hatchback because all the other doors were frozen shut and I needed to get to work. And it was a stick shift and I was pregnant. (Don't even try and picture that one). When I high-centered the car on an ice boulder the snowplow had created because I was trying to turn into our driveway and now had two rear wheels airborne. That one took two neighbors and a pickaxe to resolve and my explanation to my bewildered spouse when he arrived home after it was all done about "I just thought if I floored it, the car would go over it like a mogul." Ah, good times, good times. Just be patient with the noobs. We learn eventually.
