I actually think it's really hard to get ganked in ED.
First challenge for being victim is finding a wing to attack you.
Second challenge is putting yourself in a position to be interdicted.
Third is failing an interdiction.
If you have any combat sense, you'll know to submit.
So your FSD cooldown is normal.
The final challenge is jumping to hyperspace, no one can stop you.
If they're all running rail-de-lances, they can't target Subsystems, so just shake and boost about while charging your FSD for hyperspace, then turn and go.
It works 99% of the time.
Unless you've decided to take an unshielded T9, to Everate for a cargo run, you're likely to survive.
No 'deterrent' necessary.
On an unrelated note. It's snowing! Yay! Lol
