A friendly Sun reader, reacting to a recent column about questionable highway driving, provided this link from an insurance company.
The site explains how to optimally position your rear-view and side mirror such that blind spots are eliminated. The author states emphatically “I don’t believe in ‘blind spots.'”

If you drive, why don’t you give it a try. It might improve the field of view of your car mirrors.
