But, to restate the obvious point people are obviously denying ... if the driver sees the rider, the driver will generally not hit the rider. If the driver does not see the rider, the driver will not see the camera.
Most collisions are from the side, so the helmet-cam is worthless anyway. Most of the rest are from the rear, so the helmet-cam is worthless anyway.
You assume hitting the cyclist with the car is the only bad thing that can happen. If a person sees the cyclist with a camera he may think twice about doing other things like a passenger throwing something or a close pass by the driver. Cameras most certainly do alter people's behavior. The cameras are for the things that don't generally happen.
Also as stated types of cameras can catch all angles.
