What is a quick ticket?

I have a challenge that says to use one quick ticket. I have used ones that give me items, various ones to upgrade drivers or karts or gliders, but none of those seem to be a quick ticket.

What is a quick ticket and how do I get one?

Solution 1:

Certain cups are time-gated when added to the game, meaning you must wait a set amount of time before the cup becomes playable. A quick ticket is used to bypass this waiting period and grant you instant access to the cup. You can use the ticket from the cup selection screen when you have selected a cup which is currently under construction.
