How do cloaked ships avoid crashing into each other?
It's easy enough to answer for a squadron of cloaked ships, but what about two or three cloaked ships operating independantly (and unaware) of the other(s)?
Seems like it would be a huge problem in Klingon space with those sneaky Klingons always having their sneaky personal agendas against each other and sneakily filling their sneaky space with sneaky cloaked ships going this sneaky way and that...
CRASH!
