Driving a box truck with no rear visibility makes me uncomfortable and I'll use a spotter to reverse. If you can't (or won't) look and see behind you, you should NOT be driving in that direction. Will cameras fix this problem?
The article states that "There are nearly 210 backover deaths each year." I wonder how the overall safety of a vehicle and its driver will be impacted by the addition of a possibly distracting LCD in the front seat. Maybe fewer collisions while reversing, but how many additional distracted driving cases while driving forward and playing with the car computer?
