I used a handle bar mirror for a while. I found that I could hear cars coming a lot sooner than I could see them. Then I would swerve all over the road trying to see the car in my morror. I don't worry about it anymore. Maybe that's foolish but I don't. I don't see how a mirror is going to prevent being hit from behind by a car. It never helped when I drove cars, why would it help on a bike. I assume that some day I going to be hit and when I am I'll deal with it. Actually I have been hit twice. Both times were my fault and I was hit from the side and no damage was done. Lucky I guess.
I think It's a lot more important to be visable, ride with confidence and ride in a straight and predictable line.
