Thank you for your concern, as it stands now that local way of interaction between vehicles is at odds with the current galactic standard as noted in Book 29 (transportation), Chapter 61 (optical communication), section 5 (visual spectrum), subsection 2 (visual specturm communication between space faring civilizations and non space faring civilizations)

I will preset your comment as a suggestion to the grand court, who may agree to publish a local exception in Book 12 (exceptions).
