This info is for beginners and who didn't know:
NPCs are more aggressive in 1.4 then before, but there is an effective way to avoid them, especially for traders and smugglers. Against player CMDRs this method is restricted, because they don't need to target you to attack.
Activate Silent Running, then use heat sinks to keep your ships heat level down.
Use "A" rated power plant.
Doing this way, NPCs cannot target, scan and attack you.
