That's not my comment. I do agree with it though.

I'm not sure if you're joking but knowing if the roads will be frozen or if it's gonna snow is pretty useful lol

Ok, and F is also great for that purpose. When that's an issue, most major roads will be salted. 0F was explicitly the point where brine freezes, so it's actually perfect for knowing when salted roads will freeze. You can probably know when unsalted roads will freeze by the snow/ice around. Both are useful, but you're arbitrarily ignoring the utility of F just to defend C, for some reason. I don't know why people make this part of their personality.
