‘Automatic headlights’ don’t work in fog? Safety Question

About 40-50% of the cars we passed on the road today had no headlights on or only had the dim side lights. Do automatic lights not work in fog for these modern cars? Seems super sketchy

My 2008 LR 3 gets its right most of the time, only “bright fog” confuses it, that’s when it’s sunny but foggy at the same time. Lights also come on if rain sensing wipers triggered.
