Next, there's my favorite one, simply called Autocross. It's a tight race contained within the Maze Bank Arena parking lots, meant to be non-contact and treated as a real autocross. There are a few corners that can be cut, but that's just not in the spirit of the thing.
That's actually all I have so far, partly because I'm really picky about what's good enough to publish, and also because (excluding Autocross) I cannot bring myself to create a new track unless I can think of a GTA-related punny version of a real track's name. It just won't happen. I will update this post as I continue to create new jobs, though.
