Couldn't agree more. I got caught in a totally unexpected and very thick fog one morning, and I didn't like it a bit. It was out on a farm road that I knew well, which helped. I slowed way down and put my emergency flashers on. A local in a truck was courteous enough to stay a safe distance behind me, where I could just see his headlights, I think he was trying to kind of guard me from anyone coming up too fast behind. I was sure glad when I started coming out of that!
