What about if a collision message appears, no matter who is at fault, both planes die. That is simple and easy, and should reduce Hoing too.
The system never tulips FAULT in a collision. And once again, see the pictures because I am sure you will love taking damage when that plane 100 yards behind you collides with you.
Now think about the result of a head on, the person who avoids the collision is now at the disadvantage,so of course he will now try to do the collision, so the end result is a lot MORE collisions and whining.
