If you kill an NPC that interdicts you as part of a smuggling mission, is that NPC replaced by another? My current plan of action is that when I'm interdicted, I kill the responsible NPC if I'm allowed to do so. This means it's dead if it's either declared wanted or lawless, be it system authority, a pirate or one of these annoying fixers or whatever they are.
Yesterday evening I had a planetary surface delivery mission, and a cop in a Viper jumped in after me while I was in planetary flight mode. I couldn't boost away, and by the time that was clear the scan completed a split second later. So in the future when in planetary flight mode and something comes after me, I'll shoot first and ask questions later.
Which reminds me, what is the minimum distance for a scan to interrupt?
Oh, and one more thing: Did anyone ever try mines to make NPCs cancel their scans when they chase you?
