Charles, I do not understand the need for this technology. If mirrors are set correctly, there is no blind spot. If one can see the sides of your own vehicle, then they aren't set properly.
Properly set mirrors show a car approaching in the center rear view mirror. As it disappears from the rear view mirror, it is just appearing in the side view mirror. As it disappears from that mirror, the nose of the car is in your peripheral vision. Where's the blind spot? The car was in continuous view.
I'd like to try the LaneWatch camera, Rich. I, too, wonder about its intuitiveness. In terms of intutiveness, I hope it's better than Cadillac's old night vision technology from a few years back, which was not easy to use and bombed in the market.
