- A narrower field of vision and an earlier onset of fatigue.
- A wider field of vision and an earlier onset of fatigue.

Correct answer: A narrower field of vision and an earlier onset of fatigue.
The higher the speed, the narrower the driver's useful field of view. In addition, maintaining a high speed for a long time causes fatigue to appear sooner.
