Is it really necessary for advocacy groups to push for rearview mirrors as a mandatory safety feature on all road bikes, or are they just trying to suck the fun out of cycling by making us all look like were riding a hybrid commuter bike to work every day? I mean, think about it, if we start requiring mirrors, whats next? Are we going to start mandating helmets with built-in turn signals and brake lights? Where does it end? On the other hand, Ive heard some compelling arguments that rearview mirrors can actually increase safety by allowing riders to anticipate and react to potential hazards more effectively. But isnt that just a crutch for riders who arent paying attention to their surroundings? Shouldnt we be teaching people how to ride defensively and be aware of their environment, rather than relying on a mirror to bail them out? And what about the aerodynamics? Dont mirrors just create more drag and slow us down? Im not trying to be contrarian, but I genuinely want to hear from people who have used rearview mirrors and see if they really make a difference. Do they really increase safety, or are they just a gimmick? And if they do increase safety, is it worth the potential drawbacks?
