This is not a complaint thread, just a warning to my fellow combat pilots about behavior I have observed.
In head-on firing passes in combat, the AI does not break off. Ever. Even when not breaking off is suicide. (Caveat: I don't know if this is true for small AI ships, but it is true for large ones).
I first observed this behavior when I (in my Fer-de-Lance) was interdicted by a Master Python while on a delivery mission. It was a very tough fight, but I was winning - I was at about 60% hull and had a ring and a half of shields up, the Python was at roughly 30% hull and had no shields. We went into a head-on pass in which I reduced the Python's hull to about 20% and I lost half a ring of shields. I attempted to break off the pass, but apparently too late - the AI either did not break or actively turned into my break - I'm not sure which - and collided with me... destroying both of us.
After this, I went into a High Intensity RES for a while and watched the AI fight the AI to see if this behavior was common. As it turns out, it's not merely common, it's universal. Time and time again I watched pirate and security Anacondas boost headlong into each other, the collisions destroying one and sometimes both ships.
It would appear that the AI in large ships has no programmed aversion to collisions which might destroy its own ship. Again, this is not a complaint (I do think that's a flaw in the AI, but it might actually be a flaw to a Commander's advantage if he knows about it), just an observation of something to be cautious of. Don't enter into head-on firing passes with the AI unless you're sure you can survive the collision, because the AI will make no attempt to avoid it and may actively seek it, even at the price of its own destruction.
