I wonder if anyone has investigated the effect that back-up cameras have on mirror usage. It may be that by having drivers take their eyes off the mirrors when backing up (because they're now looking at the camera display on the dash), they won't be alert to vehicles approaching from the sides. It seems to me that this could increase the likelihood of pulling out in front of someone, and increasing that kind of crash. As with red-light cameras, it seems like there might be unintended consequences that someone should look at.
