An easy way to see why this would be useless, you'll need some sort of mirror for this project.
Now once you have a mirror, find a road with traffic on it and a clearing of 200 - 400yrds(2 to 4 football field lengths) beside it. While shaking the mirror some try to see how easily you can make out what kind of car is driving on the road at those distances, or even see the car at all. Now after seeing how difficult it is, imagine compressing this imagine even smaller to scale with the size of your monitor.
This is probably the main reason we don't have mirrors on our A/C.
