Imagine a ship travels at 1.5x the speed of light. Now imagine the signal from the "steering wheel" travels to the ruder with light speed. You turn the wheel. Before the ruder gets the signal and turns (and let's ignore human reaction time) the ship has already traveled however much distance you cover when traveling at half the speed of light. You would have an enormous lag basically. Something like that :) I'm rubbish at physics :)
