I agree with the other commenter that this goes way beyond "friendly fire". According to a Haaretz article, those aid workers were targeted 3 times in a row and I assume someone had to confirm the bombing for all 3 of them. This isn't friendly fire. I would love to see their validation data to check on their claim of 90% accuracy.

The targeting problems in this war seem much more serious than "friendly fire still happens."

It's certainly possible for what you write to be true, and the video we've seen from other targeted killings indicates that even an entire human chain of command could have missed the logos on the car, off the top of my head the USA example is when we attacked a wedding party in Afghanistan because it was close to a combat zone. But it sounds like the rules of engagement give IDF the leeway to kill up to 15 non combatants in any situation for one AI identified male in targeted age group and 100 if the male matches a high value target, which seems incredibly broad. It's all a moot point for the victims, and the IDF killing hostages with their hands in the air sounds like it's kind of out of control but could be sampling bias since reporters are being killed at a pretty high rate as well.
