I apologize for being angry, it was not directed at anyone. Okay so I finally was able to get it working halfway. When I export to fbx I have to have these exact settings (scale can be changed) or else the car will flip or break.
At least the car is driveable on my track now. HOWEVER. I still have an issue that the car will not face the correct direction when it spawns. I have looked at the local pivot in blender and made Y pointing up properly, but no matter how I rotate around that axis, the car faces some totally random direction and it seems to have no bearing on where the axes are pointing. So for instance, with Y up, I've tried making Z and -Z forward and X and -X forward, and the car will, for instance, point backward and 45 degrees to the right. So I'll turn it appropriately so that the car should be facing forward, and then the car will spawn pointing perpendicular to the road. It's very confusing but at least I can drive around and play around on my new track.
EDIT: I'll also add what happens when I try to set the rotation forward properly.
As you can see, the local rotation of the spawn object is not at that angle at all.
2nd EDIT: Maybe this is happening because I'm trying to spawn it on a camber?
