OK, it is driving me CRAZY riding without a rearview mirror. Often there are people walking in the shoulder, or a car pulled over in the shoulder, or a large pothole is in the shoulder that I want to avoid, or there is no shoulder at all to ride on, so I have to ride out into the main part of the road. I don’t know how everyone else does it but I have to turn my head around and look behind me before I veer out onto the main part of the road. When I have my head turned backwards, I am not seeing where I am going. Not Good!
