YES! A good mirror is a huge asset, elbow and knee pads are much, much farther down the list. I had a really bad crash this year, broke four ribs, punctured a lung, and had a really nasty concussion even though I was wearing a helmet. I am a great believer in helmets and I very well might be dead or a vegetable if I had not been wearing one that day but they unfortunately give you little to no protection against a concussion. But with all that my elbows and knees were just fine! Because of the concussion I have total amnesia of that afternoon and cannot say if my mirror would have prevented the accident if I had been using it at the right time or not. It may have been just a loss of control on my part, it may have been due to something an automobile did. I do know that my mirror gives me a lot of information about the traffic behind me and that makes it one of the most valuable pieces of safety equipment you can purchase.
