The Mario Kart Wii ghost glitch in action

Online play in Mario Kart Wii is smooth. Only a tiny bit of lag effects twelve player races. However, the world ranking system has issues. A glitch allows players to drive a single lap then wait by the finish line while sitting in reverse. Glancing through the rankings, it looks like Nintendo is actively removing these times off the leaderboards, but you can see the glitch in the video below.
