I'm really sorry to post this here but from a game point of view I am at my wits end with this issue. I'm only posting in the hope someone can help me
I can not avoid interdiction ever. The very act of being interdicted sends my ship into an unrecoverable spin (see image)
The above is a screen shot I managed to get about 0.5 seconds after interdiction notification. As you can see the ship that is interdicting me is up and to my right and I cam going backwards whilst in supercruise, which is something I am not even sure is possible?
The next frame which I failed to screen grab showed the hostile red ship in front of me within my cross hairs.
I have a ticket on this, a bug thread on it and have had no actual response and its driving me up the wall because it makes no difference what ship I am in and I cant even submit because it all happens so fast I receive FSD damage before the submit happens (I guess this is because I cant follow the escape vector at all).
If its not fixable then I'll just have to accept that interdiction = damage
