Various safeguards that could be toggled with a small switch on the console, maybe forced on by admins if they're feeling like douche bags
Players could also choose if there are only some safeguards on
in settings, if forced on by admins ALL safeguards are on regardless.

Would stop you from meterializing if destination was found to be unsafe such as colliding with props/world,[prntscr.com] or too many hostile NPCs nearby. Would trigger your basic cloiser/red lights warning, rematerialize where it dematerialized unless activated by HADS (if possible to detect this) in which case would stay in vortex and the basic warning would stop after a few seconds.
