I sometimes wonder if the Rules Committee lives on a different planet from the rest of us!

There is no way in hell that any contest director in the USA would mandate the use of stealth mode on an anti-collision system if this reduces its usefulness even the teeniest bit. In the event of a collision, insurance companies looking to minimize their exposure through subrogation would hold the CD at least partially responsible for the accident - spreading the cost to his or the contest's insurer. This might not be an issue in the rest of the world, but is sure is here in the USA.

No sensible person would ever mandate stealth mode here!
