"Starflae, wake up! Your heading straight for my ship. I'm going to have to ask you to change course or I'll have to do it for you, son. I'll give you three warnings to halt and disengage me."
Yes. Say he is engaging you. Do it! I believe that in the real world of Freelancer that "suiciding" or fireboating is very popular, and considered a serious form of attack (fireboating was used by the English to destroy the whole Spanish armada, you know?). Infact, when he drops your shields below 50% that gives you more than enough reason to blast him to smithereens.
