Multi Stage - Teufort Grand Prix

I've had an idea for a long while of a full Grand Prix game inside one map, and by that I mean 4 different tracks all played after the other. For example, the Grand Prix from Mario Kart (Mushroom Cup, Star Cup, etc.).

*VERSION A3*
As of right now, there are 3 tracks and an intermission area:

Badlands Circuit

It is a figure-8 track that features 2 pits and a "shortcut." The shortcut is just a route to get an 8 second boost instead of the normal 3.

Dry Dry Dustbowl

Half-detailed, but mostly blocked out. Features a modified circuit loop with a ramp that jumps over a separate paths that lead to two different mines. With multiple options for the track, which way is the fastest? Vary it up and find out. This track definitely features more specific things from Dustbowl than Badlands Circuit did of Badlands.

Merasmus's Mansion

I'm still debating on the name for this one, but it's a mansion akin to Luigi's Mansion. The track is heavily blocked out with only minimal texturing. A few gimmicks including lightning strikes, changing doors, and even HHH to keep you on your toes pepper the track. Even the background music changes to suit the spooky environment.

When I decided to make this map I needed to solve some problems associated with a kart race map. First of all, people find them boring. The solution? Make the track as small as possible. Of the other kart race maps I've see, they're all very drawn out and nothing really happens. Thus, if the track is much smaller, then it should be more interesting.

I am aware of the double-shot bug that results from testing a kart map, but there's really nothing I can do about it other than wait to test the map when an imp is ending.

I used Idolon's Aether prefab for now, but I plan to majorly modify it in order to accommodate more than one track (so for now, 1st team to 40 laps wins).
Also I used Washipato's Engie Counter prefab for the lap counter.
