Wow, I guess I really got something started. I can't believe some of the negative responses. Everybody has a reason for using and not using a mirror. The arguments against them are ridiculous. With a mirror I don't have to turn my head to see behind me and I can see in front of myself at the same time, can't do that without a mirror. So I guess when you are looking behind you and not in front of you, the car pulling out of the driveway in front of you will kill you but you showed us. Use a mirror or not but I choose to be as safe as I can be. I also have a blown disk in my neck so turning my head does not work to good.
