How can I obtain the Lightning item in Mario Kart Tour?

To obtain the Lightning item in Mario Kart Tour, one must be in a race and acquire it through an item box. Item boxes are scattered throughout the racecourse, and hitting one will give a player a random item based on their current position in the race. The further back a racer is from first place, the better their chances of getting more powerful items like the Lightning. Therefore, to increase one's odds of receiving the Lightning item, it is advantageous to be toward the back of the pack when hitting an item box. The Lightning is one of the most potent items in the game as it affects all racers ahead of the user by shrinking them and reducing their speed temporarily, giving the user a chance to catch up or gain an advantage.
