Has anyone thought of the possible disadvantages of using a bike camera? I feel more concentrated to my riding when not using a camera. When I do use a camera, I tend to keep thinking what is being shot in the camera each moment, and sometimes would turn my handlebar toward something interesting (such as a cute dog) in order to catch it in my video, which could be bad in certain situations. Furthermore, if one does use a camera, it seems to be more important to have a camera in the rear recording the vehicles behind you, than in the front. Thoughts?

(I'm talking about using camera in case of accidents, not for sightseeing)
