Turian Ark and SAM *spoilers*
Throughout the game, there are a number of times where it's stated SAM cannot act without a Pathfinder plugged into it.
It seems to me, that somehow the Turian Pathfinder's SAM, either didn't get that memo, or a pathfinder's dying wish is enough to set the SAM free enough to become incredibly dangerous to it's own people.
The Turian ARK was piloted by the SAM, recklessly through untold amounts of Scourge, killing many of it's people in cryo stasis in the process, in a blind loyalty to it's dead Pathfinder's last wish, to "Find a home" for the Turians. So, SAM points the ARK in the direction of the planned Turian Golden World, and scourge be damned, full speed ahead. Can SAM even exert that kind of control, flying an ARC by itself?
The game then just lets these implications fade away with never discussing them further.
I demand answers, for the sake of the Turian People!
