Implying that they're exclusive of each other.
In 4-player races, who won or lose wasn't where the fun was.
The fun was in getting triple red shells, hitting the person in front of you with one, and stopping, waiting for them to recover, hit them again, wait for them to recover, and then hit them again.
Or intentionally slowing down when you have triple shells active so the person behind you runs into you.
