‘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

I drive your average early 2000s silver compact car, and instead of flashing my brights, I turn off my lights entirely and pulse them on/off.

It sends the message when I literally disappear and reappear.

I will continue doing so till some unhinged driver kills me, but I'll die happy.

Yeah, that’s what I do. Around here in rural central Ohio flashing your high beams means “cop/hazard ahead” so I try to avoid doing that unnecessarily.

Sometimes the highway patrol sees you flashing the warning— even after you have passed, and cite you with a local law.

There is some federal precedent that says that’s free speech. https://www.aclu-mo.org/en/node/479

Your mileage may vary on that if you’re anywhere other than Missouri though.
