One reason I usually end up with large ships are things like rail doors, elevators, etc. Moving parts. Thing is, to make moving parts, you need lots of space to house all of the background bits that make things move (the rails, the logic, etc).
Even when I don't use rails to make large "moving" doors I use lots of logic to make the doors "open" and "close" one row at a time to make it look like they are rolling up/down even when they aren't.
And even when I don't do any fancy animation for doors, I still like having round 3x3 hatches with wedges in the corners on either side of a square 3x3 to make it look like a funcional hatch instead of just a square of plex door in a wall.
Finally, we have no good way of making unobtrusive turrets. If you want a turret that is worth putting on a ship, it has to be big enough to pack a punch, which means if you don't want a turret half the size of the rest of the ship you have to scale the ship up to make it look less obnoxious.
So yeah, combination of "I want detail", "I need room for logic and moving parts", and a bit of "Big ships are impressive!" thrown in for good measure.
