I didn't mention it in my review because it won't be in the first release. Plus, MuffinKing is right. Immature people will curse if they lose. I say leave it out.
I've come to the point where I have accepted that its better to shoot than carkill for one reason:
You are around long enough to see the other carkillers get banned (fun to watch).
Wow so only new people to the game use cars to kill? So because you aren't allowed to kill with a car, I am guessing that its obvious that you are not allowed to shoot at a car if someone is in it, right?
