There’s a repo for it maintained by ghost, but you have to do the install and setup yourself. Can’t vouch for reliability, never used it.

Pretty sure if you self host your own ghost install it’s already available.

There’s a few, mostly closer to simulation than tux kart tho. A few that I’m fairly sure are under active development:

Stunt Rally.

VDrift.

Speed Dreams. Can’t easily find the github for this one.
