If a player were to fall off their ship while cruise was enabled the ship would just fly away and be near impossible to get back, especially it it had engines on it. Could cruise be made to disable automatically when the player that enabled it leaves the ship?

Isn't part of the point of cruise to let you walk about your ship while it's going?

This wouldn’t affect being able to walk around on your ship while in motion, it’d just stop your ship from flying away if you mess up
