Yes, I have seen that video. That is where I learned the procedure in the first place.
So if I am understanding you correctly; the game is drawing the LOS line from the original position, but it is actually determining LOS from the ball?
If that is the case I am not moving the vehicle far enough forward. I'll give that a try and blame any knocked out vehicles on you. (Joke.)
And yes Usually Hapless' videos are great.
Thanks for all the replies.
