They should have quick race so you can just pick one track an then pick another person, kart, drift and track.
New Mode: Survival Mode!!! I'll explain this... Pick any of the tracks you unlocked. Something based on the track will be chasing the 2-4 players down. For example:
Last time I said Ghost Valley 1 should be in it. So if you pick it, a big boo will chase you. Every lap they get a little faster. You can set the speed at the beginning, 1-15. Example: Toads Factory Chaser: A giant tractor
DK Summit and Rosalina's Ice World Chaser: A giant snowball
