Yup, by default the setting Spruxxx mentioned is set to Notify Authorities.
If stopped in hypercruise by a npc or player, just put full throttle in engines (4 pips under power management), use booster for speed and keep hitting it every time enough power in it, also jink up and down and slightly left and right, it makes for hard target. I find can get away like this even with some big slow ships although i through some chaff out too for good measure. FSD will cool down quick enough then can re-engage it to escape.
Players who are experienced are more likely to chat and offer good advice, I would expect you should fear these less than new players trying out his new guns. For them just rinse and repeat para 2 in this response and they will get frustrated quickly, including the npcs
PS don't go for cup of tea or coffee while in hypercruise (cough), i would never do this then come back to an insurance screen..... honest.
