do you know that pathextrude would be doing this for you. both mesh generation and surface reading? Not only speaking of pathDuplicator that allows you to place all your trees, building following your track. Even Elevation can help you if you would build mixing pathExtrude and ElevationReader. In case of PathAnimator use, the only thing required would be to allow a range around nearest point of curve to allow free movement of the car along the track (your work) tree's, obstacles... they can just be a series or simple rectangles or boxes. distance checks...
I understand the BSP/awd stuff as this charming aspect regarding the automation of the collisions, but keep in mind that moving items (such as other cars) into a tree is a costly thing. also as the PVS will not be in there, because you plan work from a simple shape, and push everything inside in one single node just to get the colliders, you will have exactly the same issues as in regular scenery build (define who's visible or not for instance) and even have a bigger overhead for nothing... there are also classes such as Ray that could help you test a hit on a face, the "road" could be a non rendered simplified mesh than you use for your collisions for instance... and finally you also have the very inexpensive CollisionMap class, ideal for instance if you place irregular pools of oil, sand on the road that affect speed or trajectory...
