First, I do not believe there is much support in the canon for most
starships - even at high TLs - to be equipped with AI, let alone ones
programmed with the Three Laws.  While rules for such exist (Book 8, et
al), this does not appear to be a common feature in published ship designs.

Second, IMO, when the car, or ship, can take independent action to
prevent (or minimize) harm to sophonts - and is required by law to do so
in most cases that PCs will encounter - then I submit you are not
technically in control; you are a passenger.

"Adventure is something dangerous and exciting happening to someone
else, far far away."
