Old Spanish Trail Highway Circuit is fantasy track, based on real life location in Mojave desert, near the Old Spanish Trail Highway, hence the name of the track. You can check out the location's street view here. Background story is that circuit was made in late 1960s and abandoned right after the testing, so tarmac and basic safety barriers are in place. Other than that, not much else.
Track is great for racing, and suits well historic cars or anything with low grip and lots of power.
Features:
* Length 6313m
* Width 15-24m
* 30 pitboxes
* 2 DRS zones
* 3 replay camera sets - Drone, Ground and Static
*RECOMMENDATION* I suggest to drive after 18:00, when sun is going down, like in screen shot below. That creates the atmosphere I was aiming for. At noon desert might be too bright for you.

If you are talking about the secondary layout with tight chicanes and concrete barriers, it's made for hotlapping or AI track day at best. It is really tight and even for human with narrow field of view can be difficult at first.
There is only one tight line to take the corner, and I don't know if there is a way to prevent AI from trying to cut the corner.
Original fast layout was meant for AI racing and should be used for it. The slow layout is just for fun hotlapping, like and obstacle course, and testing out car's handling.
