It might improve the sense of speed when moving fast if the game's field of view (optionally) increases as forward ship speed increases. I think a lot of other games do this.
Took a quick look at this, it looks like FOV adjustment is already there. If you hit ~ to go to the console, you can run /fov to adjust the FOV. Should be as simple as taking the speed and using it as a base to dynamically adjust the FOV.
