>but you need to be able to see the drone

To have line-of-sight. Actually being able to see the drove is usually not possible - seeing a small drone at 40m high is near impossible after a couple hundrend meters away, especially as it moves.

Of course nobody actually tries to be able to really see the drone.

the law translated by deepl is more strict than in my memory:

> The drone must be visible to the naked eye and remain within the pilot's field of vision. Immersion flights (FPV) and the use of follower drones are possible, provided a second person is present.
