That wasn’t the plan. The plan was for her to be the decoy. She’s then flooded with the emotion of watching her people being blown to bits. Ramming the fleet in hyper-speed isn’t something that has ever been done before (to our knowledge). I’d say it is unfair to expect her to come up with this plan immediately…

She was supposed to be the decoy. Wouldn’t have made much sense for her to do that before the transport started to get hit.
