No easter eggs have been confirmed to exist on this track, but the discovery of a busted car hovering up above the track has gotten the interest of several people.
To find the broken car, go to the 4th checkpoint. Jump onto the next ramp, then jump off of the ramp and bail out while you're in the air, holding up-right on the thumbstick. You'll see the car just hovering in the middle of the air.
We don't know if the car does anything. It could be part of a significant easter egg, but it could also be a leftover piece they simply forgot in the track.
