When could a dangerous situation arise here?

In the scenario depicted, a dangerous situation could arise if you continue driving at the same speed while a cyclist is present. Two critical points highlight this risk:

1. If you maintain speed, you may not have enough time or distance to react to sudden movements by the cyclist, such as changing lanes. This is crucial since cyclists can be unpredictable.

2. If the cyclist changes to your lane, this can lead to a collision if you don't adjust your speed or position accordingly. Cyclists have the right to use the road but also face risks from motor vehicles.

It’s important to remain vigilant and adaptable while driving, especially in areas where cyclists are present. Adhering to these considerations is not just a courtesy; it is a legal responsibility under German traffic regulations to ensure the safety of all road users.
