When driving at **high speed**, one of the negative effects you may experience is the **tunnel effect**. This phenomenon occurs because, when going fast, your ability to perceive what is happening on the sides of the road decreases significantly. Instead of having a wide view of the surroundings, your attention is mainly focused on the **center of the roadway**, as if you were looking through a tunnel. This means you stop seeing the sides of the road, which can be dangerous because you might not notice obstacles or changes in the environment that require a quick reaction.

Therefore, it is important to be aware of this effect when driving at high speeds and adjust your driving to maintain safety.
