I 100% agree with these changes, that are necessary to make the world more believable and add consequences to messing up at high speed.
However I am concerned about 2 bug that would make these change extremely problematic currently :
1) When in a ship travelling at fast speed but not in a seat, the elements have the tendency to flicker or even disappear.
When the pilot seat disappear due to this bug, you can no longer take back control of your ship, so the only way to stop is to log off.
2) When jumping out of an Anti-Grav ship (anti-grav ON, ship immobile, above 1000m), the anti-grav sometime decide to stop working and the ship falls.
This bug seems a bit random, maybe linked to the presence of other players nearby.
Since my anti-grav ship is not meant to go bellow 1000m and have no way to climb back on it's own, my only way to get it back up is the use of the maneuver tool.
Due to this bug I systematically force-respawn to "freeze" my ship before jumping off.
So until both of these issues are addressed I think these changes must be postponed.
