"Hang on a minute- I have to stop and shift to 'goofy mode' so we can spin in place for a while."
Wonder what happens when you floor it like that?
What would happen if you floor it when it is in zero-turn mode?
Two big old honking pieces of cast iron, each with internal rotational inertial masses of its own, and the dynamics of conservation of energy, being forced into an ever-changing vector - those rotating masses being turned out of the original plane will force some of the components to right angles.
I would predict rapid self-disassembly and a new winner of the Darwin Award.
