This one isn't present in DS, so should it be removed?

More specifically the actual 3DS version not 3DSBC

Probably change to avoid protentional confusion.

Glitch doesn't slow down the kart, but is incredibly difficult to perform correctly, from hitting the clip correctly, to narrowly dodging the invisible wall. Not yet sure if it even saves time, though it puts the player closer to the UFO.

(No, the video isn't spliced)
