‘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

But what I really find annoying is that the dtrl only light up the front LEDs and not the rear lights.

That's because there are no day time running lamps on the back.

Exactly my point. There should be.

I looked into it a while ago and it was determined drl tail lights wouldn’t be effective in the day because they’re not bright enough. They didn’t take into consideration drivers not being bright enough to know how to operate their vehicles.

Actually this is changing now and manufacturers are turning on the rear lights now. I almost think this is a UE requirement, but not sure.
