I have to say, I wasn't that fussed about it pre-release, but I've had a blast on it on Hard and it was really good fun. Finally (after about 3 hours lol) I managed to beat Kimi. I even put in a respectable lap of 1:53.732 and finished 2.7 seconds ahead of him. I can appriciate it won't be a feature people will go back to again and again, but it's a nice new feature for a quick blast (or not so quick in my attempt!). Roll on the Lewis challange!
