People often don't help themselves either. I remember this time, I was driving on a country road in the fog. Suddenly I saw my foglights light up a dog walking in the road. So I drove around, then as I got closer I saw a man walking this dog, dressed all in black, on an unlit country road, walking away from traffic, in dense fog.
If he made it back home alive, it's purely down to luck (or his dog being seen before him again).
