Different Methods Can Conquer Blind Spot

The result eliminates the gap in your rearview sight (be sure to test it out, though). Still, drivers rarely set their mirrors this way, and some automakers have tried a technical solution. Ford, for example, has a Blind Spot Information System that uses radar to detect cars coming up from behind and illuminates a small warning light on the side-view mirror. This option runs $1,595, though.

Finally, you could also use a small mirror called a BlindZoneMirror, which comes standard on some models, like the Ford Edge and Chevy Traverse (well, except the base model). These are small mirrors that attach to the side-view mirror and are engineered to make the blind spot visible.
