Driving in fog — a 100-vehicle pile-up in Madison.

The Cap Times reports.

"I braked like crazy but there was just no way to stop," she said. Dietz Slavenas hit two cars in front of her. There were cars and trucks all over the road, some piled up and some separate, she said....

"Most people were very nice and very calm," she said, adding that someone was handing out Christmas cookies. "You run into the nicest people in Wisconsin. I love Wisconsin."

I love Wisconsin too, and people are very nice here, but they do not know how to drive in fog, as I observed when I drove to Milwaukee a couple weeks ago:

... I'd driven over 100 miles on I-94, and the fog had been much worse. I think I was the only driver on the road who was constantly thinking: This is how 50-car pile-ups happen. I drove so I could stop without crashing if I saw an accident ahead, and no one else did. People are crazy.

This is how 50-car pile-ups happen. This is how 100-car pile-ups happen.

Here is an unretouched photograph of what yesterday looked like:
