"Recently a Ford engineer noted an outside rear-view mirror increased drag by 1 pound at 65 mph and increased fuel consumption 0.05 miles per gallon.To carry this mirror on a 1,000 mile trip would cost you seven cents,the consequence of air drag."
Jack Heltemes,'ADVENTURES IN AERODYNAMICS',HOT ROD MAGAZINE,April,1962,p.35.

"We did a lot of development on the side-view mirrors because they add frontal area.We got them slippery enough so that they almost compensate for the frontal area they add."
