17: Blind Spot Mirror
The blind spot is probably one of the most annoying things for a driver to encounter. The problem is that you can damage your car or even hurt someone. As vehicle designs become more intensive, the blind spot will only become worse. Blind spot monitoring systems help, but they are available on every car model (via The Sun).
Blind spot mirrors have been designed to help you sort of aid in the spots you can’t see. Originally designed for truck drivers hauling a load, these mirrors have now made it onto many cars. The end result is a mirror that will help you see your blind spot and haul a load properly.
