Escaping is a non-issue. Problem is the <Ahem> chain interdiction. So many AI queuing behind me to <Ahem> me all the way to the station. 1 or 2 interdictions with a breather in between is ok. But when you get 3-4 interdictions back to back and they chase you all the way to the station interdicting repeatedly, thats where <Ahem> go down. Those AI ships are for the most part harmless, sometimes they get off 3-5 cheap shots which is nothing. But stack those up with multiple chain interdiction and we have a problem. Even as i am landing on the outpost, the AI is there, 2-3 of them if i'm unlucky, unleashing their firepower. You guys say the AI is awesome, is skilled, is improved. Well i think the AI and you have no common sense or brains. If you're a pirate and keep being epic fail in your interdictions cos you let your victim slip from your hands, common sense dictates you might as well give up and move on to another target.
Though all this doesn't happen often but its still annoying enough to warrant a change.
Stacking missions, will increase the risk.
Yesterday, I had 3 missions, with 3 different threats and fortunately, 3 more credit bonuses

to add to my haul. One was an Elite FAS, which I had major issues running from. I tried the '0' throttle and running tactic and lost 25% hull in the process. Then he pulled me again and tried to fight the pull, only to have an FDS failure without warning. (working as normal there then) So having never taken on an Elite FAS, I chose to do so. Yes it was hard, in a less that top spec Clipper, but to me, it was do or die. This pest, was going to be dealt with, one way or an other. I finished the mission with 15% hull and another 50k in the bank. I know, that if I had continued to try and run; that FAS would have worn down my hull to 0%, with its constant pestering.
In short: You make your own choices, take your own risks and reap, your own rewards. If you are doing something and continually failing, you may need to re-think what you are doing, or how you are doing it.
