Buddy of mine who works with the high tech eco cars tells me they should spend more time shaping the rear than the fronts. Look at airplanes and the super high eco test cars. They have aero fronts but rear shape to match. Maybe the trailer designers are missing something.
I was about to say the same thing. A flat rear end :W causes a vortex which creates suction. You'll see on some semi-trucks they have these weird looking fold out things on the back of the trailer that helps to reduce the vortex created in the back. As somebody below pointed out, it's the same reason airplanes start with a point and end with a point.
