I love it, finally a UI that doesn't punch you in the face! I'd love to see more of this (I think of the drift mode and drag mode UI). If i have to nitpick, something looks off with the flags text. Maybe it's aliased, or the colors aren't right, i can't tell. Maybe it just doesn't need a subtitle? If i read "chequered flag" there's no need to know that it means "race finished". Oh btw there's a typo there :)
Keep up the good work!
