The other day, I had a car suddenly appear in front of me in the fog, it was showing no lights so wasn't visible until about 2 car lengths away.
When I checked the footage on my Mobius, the cam had spotted it 6 car lengths away.
Another time, I braked hard as I thought I saw someone crossing the road up ahead. They were wearing all dark colours & I thought I saw something passing the headlights of oncoming cars. Only when I got close up did I see the little old lady dragging her shopping trolley.
Again, reviewing footage, things didn't look anywhere near as dark on cam - you'd be forgiven for asking why everyone has dipped headlights when it's not that dark. And the kicker - you could see the little old lady from a fair way away!....
