Wing mirrors are always getting damaged and stolen.
Today’s invention makes use of the fact that certain rear-engined cars already have a filler cap in the wing.
This is used to accommodate a driver’s mirror which rotates out of the wing when the ignition is turned on.
Its rear face is aerodynamically sculpted, so as to reduce drag.
When tha car stops, the wirror is secured back in the wing.
Refuelling requires opening the lockable mirror and putting the nozzle in the duct indicated.
