Well. I think that people who makes the game have provided lots of AI "flags" but didn't had time to setup all of them.
Because nobody know how this AI works, you should trust the propertie name.
Wilderness <=> if a car have too soft suspensions then it'll try to find another way. For example.
This may be right for original cars but custom cars will surely acts wrong because it's impossible to know how to setup this.
The only thing I can say to you is : try and see how it works. Then change the AI node propertie and try again...
Maybe you should ask Manmoutain too about this. Good luck !
