I disagree with there being no danger at 5nm.

Depending on courses and speeds that 5nm could go to zero in as little as 16 seconds or so. Airliners are not especially maneuverable.

Yes, the odds of the courses actually intersecting are small, but not zero.

Yes, of course that’s my point. We have to draw large safety margins around these systems, and then we have to treat incidents that breach those margins as seriously as we would an actual collision.
