What must you note when overtaking the cyclists in this situation?

Your answer is correct. When overtaking cyclists, especially on inclines or uneven roads where they might sway, it is important to allow a wide enough safety distance. The German traffic rule requires a minimum side clearance of 1.5 meters to protect cyclists from being endangered by passing vehicles. Since the incline causes the cyclists to sway, this additional clearance is particularly important to avoid accidents. The 1.0 meter clearance is not sufficient in this situation because it doesn't account for the swaying motion. Always ensure you give cyclists ample space when overtaking, especially on hilly or narrow roads.
