In my opinion NPC's should only be around certain specialized areas be nasty. Be it secret hideouts or military system, or the "special parts of the Omicrons" where usually you shouldnt be. There I imagine NPC's should all be giving you a hell of a ride. But not around your usual role play hubs. I also disagree with adding CD's again, this will be more annoying than anything. Backwater systems, military systems and war conflict zones yes or maybe some secluded fields with x secre hideout in it, but not on public routes or common rp spots.
