EvE expert here, in addition to this, safe spots are created by warping between two points and using the “save bookmark” feature to drop a pin mid-warp. You then turn the ship around to warp to the empty location you saved. Making multiple safe spots and warping between them will drag you away from common warp vectors and celestial object allowing for some truly remote locations. This is important for being able to run and hide until your aggression or log-off timers expire (without a cloaking device).

Back in the day there were exploits that would allow people to throw themselves more than ~14 AU away from objects you could warp to and make safe spots. Most of these have been removed from the game but the ones that remain are golden tactical tools for Fleet Commanders and are worth a ton to keep secret.
