And there's many solutions if FDev would actually care to try and fix this poor mechanic. One would be simply move the distance one arrives at when exiting SC at a station - make it 20x further or something where pirates could try and wait in ambush or blockade, and where the player would try to either run the blockade, wait things out, try a different approach angle or bail and look for another destination. This would add a lot more gameplay options. But FDev simply love their interdiction mechanic 'as is' it seems, and it's really the only interactive 'thing' ever developed for the game.
The idea of dropping into a station instance further away & running the gauntlet in was originally in the game I believe (pre-release), I don't know the reason why it was changed but it could help improve the chances of successful piracy (it wouldn't make it worse
I'm happy with the state of interdictions, NPCs are relatively easy to evade (compared to players) but there is an advantage to submitting anyway (interaction) and fighting the interdiction uses the same basic skill as flying (smooth, controlled inputs). With players the attacker having the advantage (making any interdictor more likely to be successful) just means more interaction too, which is a big part of what the game is about (ie why it's multiplayer).
However the flight model in Supercruise is very basic, with no drift, a fixed model per hull and no reverse. I'd like to see the Thruster grade & engineering affect supercruise flight characteristics, although perhaps not in every way. Acceleration rates should probably remain unchanged, and reversing would fundamentally change attack & evasion tactics in imo probably a negative way (I think it would significantly favour the would-be attacker overall). But I sure would like a way to make my ship turn faster and actually fly around gravity wells rather than pointing the ship as though it's on rails.
I don't want a change that favours the attacker or the victim, but I would like to see skill play more of a part in regular supercruise flight. Maybe then a reduction in NPC interdictions could be justified, because simply navigating through supercruise would stave off the boredom that the occasional NPC interdiction currently achieves.
