[Suicide Junkie]

Random and non-random movement is applied between turns.
You can use this to save fuel, by letting a black hole pull your ship towards the middle and then powering out through the other side in one turn. You get a couple sectors of free move.

Damaging sectors do typically cause ships to stop.
I'm not sure if a ship will stop when it is hit with only a tiny amount of damage and suffers no component losses.
