Evolving car wreck is a great analogy. I remember once getting onto ice in my car, and there was nothing I could do as I pirouetted through a complete circle to end up broadside on across the opposite lane.

Fortunately there was nothing coming....

But it was that feeling of helplessness coupled with a sort of detached horror that comes to mind...
