it wasn't at 100 feet...if he was at 100 feet... he wouldn't have hit me..
On HIS computer he completely missed you.
So, lets reverse the pilots. You are the one flying and the other guy is on the runway. You pull up at the last second and avoid him, but on his computer, due to the distance/time element, he sees you hit him and so he dies. Well now, out of the blue, after you have passed him, you explode.
Your next venture to the bulletin board will be to yell about how you avoided the collision and yet died anyway. Would that be a fair statement?
Right now you have absolute control over whether or not you collide with someone. Using your solution, you give control to another player and take it away from you. There is no way you will convince anyone you would be happy with that.
