So, this is the reason why there's a fog light on the vehicle ? I once had this kind of situation when I travelled with a group of friends in the center of Aceh (highland) to go to West Aceh. It's a mountain road though, no traffic no other cars/trucks or bike at night. But the fog was as dense as yours, less than 2 meters to see ahead. It's scary, tbh. Fortunately, our driver was a well experienced one.
I think those who are involved in accidents are probably less experienced and impatient on the road. I'm glad that you are safe.
When I took my riding license, the officer told me that the most important thing you need to have while riding or driving is consciousness. You have to be conscious that the road is not yours and you gotta be careful to not harm others.
I hope you have a blessed day❤️
