What I find that is annoying, you submit, you may fight for awhile, get his shields down and some of his hull, but then you may be losing your shields also, at which point I usually cut and run. Jump to SC and of course, the yahoo chases you, your shields haven't fully recharged, but not only are his shields recharged, but his hull is at full health as well. Its extremely stressful if you're not in a combat fitted ship and are just ferrying cargo and/or doing missions. I can generally beat the interdiction in most of my ships, but I have a few, the Defender and T9 are prime examples of ships that are difficult to beat an interdiction with.
