So the cable is removeable for added weight savings....
In an accident, it roughly keeps the frame behind the passengers as a parallelogram; at worst it lets one frame rail bend inwards without disturbing the other, and eliminates one frame rail bending outwards without pulling the other rail. It doesn't look like the cable it too firmly attached except at the ends, so the rails could spread somewhat. I'm still curious. While I can grasp the spare tire being a crush/crumple/shock absorber aid, at the same time the doubts I have are because 1) I think the wall between the spare and the fuel tank is not going to keep the tank from damage, and 2) I don't see how the cable and spare tire interact in a rear accident. Where is our in-house CAD-CAM guy?
Maybe the cable is to shear the legs at the kneecap of the person rear ending you?
