(btw. i'm at no point advocating for not flying in open. open is VERY safe at almost all places in the galaxy. but the expectation, that an exploration ship being safe for pve would provide the same if encountering a hostile player is just wrong - damage per seconds, availability of special tools like fsd-disrupting missiles and so on is a totally different level - more so if you encounter a player who has build their ship only for destroying other player ships, while you sit in a ship build for explroation mainly. there are some builds though, but those will require a very competent pilot to escape, and they are still nowhere to get into combat with a player in a pvp-build. the likelyhood of encountering a pvp-player when exploring is almost zero though - if you are not at "busy" places, like a very recent discovery, a CG in colonia and such.)
For a while I was considering a career of a ganker at Beagle Point... But taking into account how long it took me just to get to the engineers with my "limited jump/limited fuel scoop" FDL build, I quickly dismissed the idea...
