It seems the original post was incorrect, as users can speed up their item wheel by pressing buttons: Original post for reference: Warning: Spoilers inside! UPDATE: I was wrong in certain places, it seems that players can speed up the item wheel by mashing the L button, however this does mean you'll end up using the item without knowing what item you got. The video has been removed to prevent misleading users. Original post: So there's been some discussions about whether or not the AI RNG system in Mario Kart generally is unfair with some going as far as calling it "AI Cheating". It's quite difficult to calculate the exact distributions of these seemingly random events so I can't conclusively measure RNG elements, but something we can accurately calculate and scientifically reproduce is the speed at which characters can use items. This is something I've noticed in every match, AI characters are able to use items after touching item boxes much faster than player characters. For players, there's a slot machine animation that takes a while before the item is assigned and useable. For AI characters, they are able to equip and use items almost instantaneously after touching the item box. For the sake of scientific comparison, I recorded footage of both players and AI characters obtaining and using items. The timer was started at the frame in which the character touched the item box, and ended as soon as the item appeared in their hands. Measurements were taken at the very beginning of the match so that characters did not have any item equipped prior to measurement (video demonstration was recorded later in the match, however none of the characters had items equipped prior). I found that players need to wait 3.4 seconds before an obtained item became useable, however for AI that delay is drastically reduced to 1.2 seconds. That's almost 3 times shorter than for human players. Here's a video recording of the timings: (exact timings start at the 32 second mark) 2 seconds isn't exactly much, but when it comes to shaking off an AI behind you with a Red Shell, that split-second waiting for your next defensive item to become useable is crucial.
