It was more foggy this morning than j yesterday. People were still plowing through the fog at excessive speeds.

I read a study years ago that found that people tend to increase their speed in fog rather than decrease their speed. They reasoned that it is because the same part of our brain that determined depth perception also determines how we judge speed. The fog messes with our sense of speed.

So the moral of the story is, don’t rely on your senses, use your speedometer.

Pilots have a similar problem flying through clouds and fog. They may even lose orientation of up and down. They have to believe they’rye instruments more than the senses.
