That’s more of a self-inflicted threat in my experience. In the 27 (IIRC) weeks, I spent fortifying for ALD, I think I
might need both hands to count the number of times I was interdicted by an NPC, which was still greater than the two (very nice) players that interdicted me during that same period of time.
But then again, I don’t fly like I’m going 30 down the Autoban while complaining that “Frontier doesn’t respect my time!”
I had a C rated Cobra III myself, though with A rated thrusters, power distributor, and a military-grade hull. Can’t say I recall ever being fired on at stations, but then again I never obeyed local speed limits, even when my motto below was more costly.
