I don't know about you guys but 50 years of driving without a backup camera and with my first new car in 20 years equipped with a backup camera, I find out that I still am not fully comfortable using it exclusively in backing up. I still find myself using the mirrors more than trusting the camera. If I do invest in a camera, it will be a supplement to my passenger side mirror for the blind side. In my opinion, more useful.
