The other scenarios on when to use fog lights, sure. Perhaps I'm wrong on. But it seems odd that fog lights on a foggy day aren't recommended nor the appropriate use. I'd assume that's at least the most appropriate day to use them.

They ARE for days like today (this morning), just not in the way you’re thinking of them. They only light up the road directly in front of your vehicle and are made to cut “under” the fog so you can see lane marking better, but they don’t really help you “see” in the fog at any distance that makes a real difference. Obviously, the faster you go, the more the benefit of being able to see more clearly only the space directly in front of you shrinks.
