Tunneling can easily happen in any physics setup if things are moving fast enough - and with giant pizza peel hands, the rotation alone was causing things to move too quickly. And in general I don't think it makes sense to use a physics simulation for UI elements like that. You want the behavior to be as reliable and deterministic as possible, and that's easy to achieve without a physics sim for simple interactions.
