What should you do now?

Your answers are correct because when another vehicle is overtaking you on a two-lane road, German traffic rules require you to make the maneuver as safe and easy as possible for the overtaking driver. This means you should slow down slightly to give them more space and time, and you should steer as far to the right as it is safely possible to create a wider gap. Accelerating during an overtaking maneuver is not allowed because it could endanger both you and the overtaking driver. Staying predictable and cooperative helps prevent accidents and ensures traffic flows smoothly.
