When I am driving a car behind a cyclist, I can never see if he or she is wearing a helmet mirror, so if the cyclist doesn't turn around and make eye-contact with me, I have no idea if I am visible and if it is safe to pass. When I see a bar-mounted mirror and I see the cyclist gazing in its direction, I am FAIRLY confident that the presence of my automobile is known. Helmet-mounted mirrors just don't announce themselves as boldly and blatantly.

Honestly, I think daytime lights AND mirrors (bar or helmet) should be REQUIRED on all bikes ridden on the road; but as long as they aren't, I'd like drivers to know that I am using one.
