You must lack skill. So far my Salvager/Ptran/Shire/ZBT/Gallic train/Uruz, and ALG hauler have got away from caps. Some lawful, some not lawful. You can outrun in Thrust, and if they cruise to catch up, they got no guns, and you again get out of range before they can fire. It really is not that hard. Just run ahead until you can cruise, or get to TL. upon exiting TL, shoot it behind you, and that gets you another 5-6K. Only time hard to get away from a cap is if they got multiple caps, or fighter escorts. And i am sorry, but caps or not multiple ships was always a loss for a solo transport.
