Alwaysfirst, your 1st one would be a good road circuit, too. Why not resize its scale to make it suitable for WTCC?
Buggy Guy, I don't do dirt tracks - in fact never have.
But what I do in real life in my summer holidays is riding my bike on my self-designed track loops through the countryside (that include sprints, hills and offroad sections). In real life, I'm more of a non-motorized kind of guy.
No, I'm not going to post these "track designs" on here, since they are completely offtopic.
