This is where the discrepancy in reality or lack there of resides.
Unfortunately, As this has been noted that "What you see is what you get", would also mean "If you don't see it you don't get it".
Sorry, but there is no way in hell you are going to be happy, if you successfully avoid a collision, by 50 feet and then blow up because the other guy decides not to avoid the collision and takes you out.
What you want is to give the other player control over what happens to your plane. Right now, you have control over whether or not your plane collides.
As much as you are complaining about the current collision system, I can only imagine the tirades if we gave control of your plane being blown up to the other player. That is essentially what you are asking for.
Unless you are asking for every computer in the world, connected to the game, to have the exact representation of the game at the exact instant in time. That would be cool! Now,...tell us how to violate the speed of light and we will be all over it, while you are receiving your Noble in physics.
I am not trying to be a smart-aleck or disrespectful, but I cannot figure out what the heck it is you want. First, you complain about players "ramming" you and them not dieing, then you want to give those same players the ability to destroy your plane by "ramming" you so you will die even when you avoid the collision. Quite the conundrum.
