I just can't get my head around the difference in complexity. The bike took literally 15 minutes to put new pads on all three disks. The car -- which was old enough to have drums front and rear -- good lord, that was a two-man job that took most of an afternoon, what with the bleeding and the springs and ... yeah, what you said.
I can't think of any (even theoretical) advantage of drums that would make up for that.
