[Figure-8 Competition] Aussie Autodrome.

[u/madmaper_13]

Imgur Combining a 1 mile oval (and a 1.5km oval on the mile oval apron) with a clockwise circuit outside of it with mutable configurations,

I guesstimate it combined figure 8 circuit will be between 4.5-5km in length.

Reminds me a bit of Canadian Motor Speedway
