Hide others car in freerun duel

[SkillZ]

This is similar as "Hide others car in race", but this work only freerun duel. Because the player lost focus on duel and can lose the duel battle easily. 
Example: Player X Challenges Player Y with his max manana vs max manana, but some anothers player stay in front of Player X to make him lost focus on his duel battle and can't win either.
