Final answer:
When driving in fog, it is important to shift your gaze instead of staring to maintain good visibility and situational awareness.
Step-by-step explanation:
When driving in fog, it is recommended to shift your gaze instead of staring. Staring can limit your peripheral vision and make it more difficult to see objects ahead. By shifting your gaze, you can scan the road and keep a better situational awareness.
This technique is similar to what happens when you look at a moving object with one eye versus both eyes. When you look at your finger up close with one eye, it appears to move more than when you look at it with both eyes or from a distance. This is because your brain uses the different perspectives from each eye to determine the distance.
