They've got to meet an aero profile as close as possible to the perfect teardrop. Letting the roof drop any more steeply than that produces a lot of turbulence and drag where the air separates from the roof.
Couldn't they make the roofline blend into the rear of the car, below or directly at the bottom the driver's sight, or would that affect the aerodynamics too much?
How bad the visibility is depends entirely on the car. My first-gen Insight has it too, but because the car is low, you get a perfectly good view out of the top part of the screen. And the divide in the middle is perfectly placed to blank out the headlights of tailgating cars...
"I would gladly give up aerodynamics for visibility" is a bit of a mushy statement though. Arguably the visibility that matters most is out the front and side windows first, followed by over-the-shoulder (since it's much more dangerous passing than it is to be followed by something), and then out the back. Provided your rear view isn't blocked entirely (which it isn't in those cars with divided windows), there's little wrong with biasing that area of the car towards aero.
I've only driven sedans so far, so I personally wouldn't know about the rear visibility in hybrids. I guess blocking the headlights of tailgating cars is a bonus, although it was probably unintended by the designers. Can you see the turn signal with that pillar if the car isn't in your side mirror?

I was more concerned about safety than styling.
