What should you do now?

Your answer is correct because when another vehicle wants to overtake you on a German rural road, you should do two things: slow down and drive as far right as possible. According to German traffic rules (§5 StVO), the vehicle being overtaken must not accelerate to hinder the overtaking maneuver. Instead, you should maintain a steady or reduced speed and position your car toward the right edge of the lane to give the overtaking vehicle enough space. Accelerating could be dangerous and is against the rules because it may force the overtaking driver into risky situations. This ensures safety and smooth traffic flow.
