Actually if you travel with Rick in his H1 you will notice how the trail is wider after he goes through. You will also notice a custom paint job of neatly placed scratches all the way down the side as well as a few major dents that some boulders managed to push that aircraft aluminum the wrong way
It's all good as long as he goes first.
BTW, I doubt a Rubicon would get stuck. That short wheelbase really helps over certain terrain that's why I want to see one in action.
