There's no sense of immersion if the game does not even make the most simplistic attempts to emulate realistic motion. I'm not looking for perfect Newtonian physics, but this is just way out there.

It is in line with SE4 physics, though.

Newtonian physics can be done fairly well in a mod.
Just give the ships infinite top speed, and zero acceleration / turn rate. Then give the accel/turn abilities to engines.
