And then there's all this: http://en.wikipedia.org/wiki/Driver_visibility

It's more than the mirrors, and unless you have transparent pillars on top of the car (giving up the structural integrity of the cabin) it's going to have blind spots.

Also, most side-view mirror blind spots are caused by improper mirror positioning. If you can see the side of your car, or see the same object in both the rear view and side view mirror, you've positioned them wrong.

You should actually have them a lot farther out such that visibility in your side mirror coincides with losing rear-view visibility. That position is a lot farther out than most people think and is tricky to do the first few times.
