Show answer and explanation
Correct answer: Yes; the field of vision decreases as speed increases.
Yes, it narrows it. As speed increases, your useful field of vision narrows, and you can only see the center of the road clearly. This is called tunnel vision. In the image, the road ahead is clear, while the sides are blurry.
