What effect does increasing your vehicle's speed have on your field of vision?

Increasing your vehicle's speed decreases your field of vision primarily because higher speeds reduce the amount of time you have to observe your surroundings. When you travel faster, the perspective changes rapidly, making it harder to take in details, spot potential hazards, or react to changes in the environment. This effect is compounded by the fact that your attention is often focused ahead on the road, which can limit your peripheral awareness. It’s crucial for drivers to recognize this risk, as a diminished field of vision can lead to increased reaction times and decreased situational awareness, ultimately impacting overall safety on the road.
