What can result from driving for a long time at high speed?

Driving for a long time at high speed can cause you to lose your feel for how fast you are actually going. This means you may underestimate your speed and not adjust it appropriately to road conditions. Additionally, high speed often leads to following vehicles too closely because the distance covered in a short time is much greater, which reduces your safety margin and increases the risk of rear-end collisions. Your reactions do not improve with sustained high-speed driving; in fact, fatigue and reduced concentration from prolonged high-speed driving can worsen reaction times. Therefore, it is important to maintain appropriate speeds and safe distances to drive safely.
