Why is it not advisable to change lanes frequently?

Changing lanes frequently increases the chance of making mistakes, such as misjudging the distance or speed of other vehicles, which can lead to accidents. Additionally, the small time saved by constantly switching lanes is usually not worth the increased risk and stress. Lastly, frequent lane changes can surprise or confuse other drivers and create dangerous situations, especially if done without proper signaling or checking blind spots. German traffic rules emphasize safety and smooth traffic flow, so it is advisable to stay in your lane unless a lane change is clearly necessary and safe.
