Also interestingly, this accumulation of energy in front of the vehicle is the cause of Sonic booms. Acoustic waves, and pressure dispersion in general, get accumulated in front of the craft, momentarily creating enormous resistance and temperatures as it passes the speed of sound. Of course the accumulation of light is different in that it can't affect the vehicles themselves due to the principle of relativity (constant speed of light for all inertial observers).
