Continuity mistake: When the Batmobile arrives on the pier, it's parked with its front end facing open ocean (against the orange contraption on the dock) and its tail toward dry land. But when Batman and Robin return and phone the Navy, the car has reversed direction (tail now against the contraption). It's not likely Batman would arrive back at the pier, start the car, turn it around, park in the same spot, shut the car off, reopen the doors and then make a call, only to then drive away.
