They are twin-level drive-through on the freight decks but the passenger car deck is astern of the accommodation, isn't drive-through and is accessed via ramp from the upper freight deck. Although things seem to move pretty quickly from what I've seen they aren't entirely free of waiting and occasional reversing around the upper deck if they want you in a particular corner.
The rest of the ships are quite beautiful though so worth any minor car deck issues.
