F1 2012 Ghost Mode for Serious Racers, please !!!

I love F1 games, and 2012 version does it good online. On the other hand, many young drivers, rookies and newbies race, and they ruin serious racers' fun by hitting from behind driving fast, and many others chain reaction collisions kill the buzz of the game on the very first chicane.

Once there was a "ghost mode" where players could race without touching each other, still benefiting the drafts and other physical realizations included, the fun was on the roof. So, the real race fans could show themselves how fast they could go, and no rookies make us suffer during the game.

Why there is no "ghost mode" available ?

PLEASE CONSIDER !
