I rented a car once that had blind spot cameras in the outside rear view mirrors -- when you turn on the turn signal, it displayed the camera's view in the multifunction display in the middle of the dashboard. It had a better field of view than the mirror, and made it very easy to see if there's a bike or pedestrian beside you. Since it was just a rental, out of habit I still turned my head to look, but it seemed like a useful. I think it even flashed and beeped a warning if there was someone in the blind spot, but that may have only worked for cars. I think these systems should be required for trucks and other large vehicles that have a large blind spot. http://www.carblogmy.com/honda-blindspot-display-system/ http://www.carblogmy.com/honda-blindspot-display-system/
