Thrusters should stop using fuel when speed limit is reached
Thrusters should stop using fuel when speed limit is reached. You are not getting any faster so it doesn't make sense that the energy/fuel just disappears. That way you could hold space during takeoff without wasting fuel.
Currently you have to use thruster override or tap space from time to time when the speed is too low, which also means you can't have inertia dampeners on. (Which can cause you to drift sideways without noticing)
To make it a bit more realistic you could also make the thruster flame decrease when the max speed is reached.
