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

Driving for a long time at high speed can lead to specific risks. The first two options you selected illustrate key dangers:

1. You lose your feel for speed: Prolonged high-speed driving can desensitize a driver to the actual speed they are traveling, making it harder to gauge safe distances and stopping times.

2. You drive too close to vehicles in front: High speeds can encourage drivers to maintain inadequate following distances, increasing the risk of rear-end collisions, especially if traffic slows unexpectedly.

These factors are significant in German traffic regulations, which emphasize safe distances and awareness of driving conditions. It's crucial to ensure that drivers are aware of their speed and maintain safe distances to prevent accidents. The third option, "Your reactions improve," is misleading; while some may think that driving regularly at high speeds enhances reaction times, it often leads to a false sense of security and poorer decision-making. Thus, the combination of the first two options accurately captures the dangers associated with high-speed driving.
