I suggest adding an eject option to HV's and SV's, if the ship still has a core the player could press "Control F" or "Alt F" and the cockpit would be destroyed "ejecting" the player, if the core is destroyed it could be automatic. The reason for this suggestion, many years ago the option to exit a moving ship was removed from the game, making it impossible to exit your craft while it's under attack if the shots keep you moving. This last play though, I was jumped by a drone, and while fighting it I got too close to a PV and it shot me while I was moving in a circle, it hit my core and I lost control of the ship, so there I am spinning while the Drone and PV attack me, unable to get out of the ship and into the hole in the asteroid near by until they finally killed me.
Yes I like this idea of an ejection seat, but problem currently is: there is very little happening on planets anyway at least in the vanilla game to make it worth, and in space usually it's your ENTIRE ship that gets destroyed, and ejecting you will only delay the kill on you. Enemies have a 100% hitting success if in line of fire and you are not moving fast, that's the thing that would have to be changed first.
back when you could get out of your ship while it was moving, (and the game was harder back then, more drones attacked you at once) I almost always escaped by exiting the ship while it was under attack, in my last play through where my ship was left spinning without power because the core had been destroyed, I still could have gotten away if I could have gotten out. But I also keep "decoys" and "walls" ready to spawn in my BP factory, you just have to move fast once your out. I would say about 70% of my deaths to drones and PV's are because I can't get out of my craft.
If you're not using factory storage cheese, though, there's little point in leaving the ship. It's not going to get you out of danger. Even if it did, nobody is coming to rescue you and you most likely can't do it yourself. The getting-out-of-danger part is probably easy enough to solve, though. Have ejection move you to a random spot ~1.5 kilometers away. Whatever disabled your ship will be well out of range that way. Not guaranteed safe, but it's better than catching the next missile. Simplest solution I can think of to the rescue issue is probably an emergency teleport transponder. Activate it, stand still for ten seconds, it sends you to your home spawn location. It's better than just dying because you take your backpack with you. Probably a great thing for players to include in a space fighter's emergency supply box.
even without the factory storage you still stand a chance if you can get out before the ship is fully destroyed, especially if you are close to an asteroid (if you are in space), and have a drill on your hot bar to dig quick. in many situations there are many ways to keep from being killed once out of your ship, in some you are correct, nothing you can do. but survival depends on getting out of the ship while some of its left. But I do agree that like a real ejection seat, if implemented this should actually Eject you from the craft and move you away.
It's really just a matter of getting out of range. One and one half kilometers is outside the max range of any turret. If an ejection system can get you that far away somehow, it's good enough to get you out of immediate danger. You're on your own after that. A different idea. Instead of picking a random spot far enough away, you're dumped into an escape pod. It's invulnerable and isn't targeted by turrets. It moves at max SV speed and can't be slowed, only steered. The catch is it only lasts twenty seconds. So get a wriggle on. An ejection system like this could probably even get you to back to space from a planet's surface if you wanted. Just the thing for getting back to a carrier in orbit after an SV raid gone awry.
That would work too, might be better to do it that way, have the "escape pod" look like the cockpit, and destroy the cockpit on the craft.
