Unfortunately, if a car is going to hit you from behind, there really isn't much you can do about it. As Slan observes, the mirror view of a car approaching quickly from behind distracts from what is in front and to the side of me- the very stuff I CAN make maneuvers to avoid.

Also, the field of view in a mirror is so small that I'd never make a lane change based solely on what I see in the mirror. I'd look back first. So then, what's the need for the mirror?
