You're driving a multi-dimensional craft. You must have a direction and a course, if not an end-target. If not, you could hit anything. Tear space. Destroy lives before they're lived, or whole civilizations in their fledgling years. Supernova all the stars in entire universes at once. You could break time. You cannot "joyride" the barge.

This is not just a boat. You are not on a planet, where you could hit a rock or kill a shark. You are between universes, and if this craft is lead astray into a system with life, the collateral will be in the billions, as a conservative estimate.

I don't think you intend to hurt anyone. But I'm deeply concerned you will hurt many by accident.
