The TT mirrors also make the truck a PITA to park in tight spots.

*Folding the mirrors on Spirit-I dropped the drag from,Cd 0.268.to 0.251.Deleting the mirrors dropped the drag to Cd 0.24.Delta-0.028 in all (11.67% of total drag) Ouch!!!!!!!!!!!!!!!!!!
*The replacement,SCCA racing mirrors added back, Cd 0.01 to the truck.
*At the time of Ford's Fusion,Bonneville LSR hydrogen racer,both GM and Ford claimed Cd 0.015 for dual outside mirrors.
*Tesla,Chevy Volt-II,Jaguar,Aston Martin,and a few others,have mirrors in the Cd 0.01 range.This is an outgrowth from the 1985 Subaru XT,which moved the mirror body out to 80-mm from the body sides,on slender stalks.
