Large meshes can take a while to be converted into physical hulls[1]. I notice this with something like Nebadon's racer (linkset of meshes) -- riding the car makes it physical and the CPU maxes out for a few seconds and the car is unridable until it is meshed.
So, if there is a problem, it could be that the vehicle mesh has to be read in (from cache or asset store), converted into a mesh, then converted into a hull. All the while, your NPC is trying to sit on it. There is no programatic way to tell if a linkset is fully physical and operational. All I can suggest is adding some delays if there are problems. -- mb [1] If you don't supply a physics, hull representation of the mesh (possible with the mesh file format), BulletSim uses a HACD algorithm to turn the mesh into a set of convex hulls. This algorithm is recursive and, sometimes, slow.
