Visibility and Contrast

Fog has a dangerous effect on our speed perception. Much of how our brains judge speed is by the contrast in our surroundings, such as trees or buildings flashing past in our peripheral vision. But in foggy conditions, contrast is greatly reduced giving the impression you are driving slower than you actually are. Many drivers increase their speed as a result.
