Speaking of the burn drive... I've had Cerberus hulls, and other ships with burn-drives. Not use them while retreating. Even when set to retreat. I tell them to run, they don't run. I'm not sure if it's just that particular battle or not, but... I'll try a few games and see if it's replicated, or if it's in only Civilian ships that use the system to escape (EG the Tarsus).
But it's something I've noticed in my games recently... I'll give it another look before I say for sure that they don't use it to run.
Correction: They do activate it, when they are going to be surrounded or have many vessles on their tail. Though the AI still doesn't activeate it ASAP when they're free to do so (EG open space and I'm distracting majoirty of the ships and the nearest ones to them are slow buggers. *lashers, brawlers etc etc*) Doesn't make a lot of sense to me. But, it's something I've noticed...
