You do, if you fly at all. Look at the names of the main parts of an aircraft: Fuselage, empennage (tail group), nacelle, aileron. They had developed the hinged aileron while we were still paying royalty to the Wright brothers for their system of wing-warping to bank the plane. Remember that in WWI we had no combat aircraft of our own and had to use Nieuports and S.P.A.D.s acquired from France. If you could see the plate on Rickenbacker's SPAD at the Smithsonian it would read: Societe Par Avions et Derivees.
Do you drive a car? Then you likely use a differential gear which originally came on the De Dion Bouton. The defroster idea came from an early race at Le Mans. French engineering has been superior in the past, why shouldn't it be good now?
I think that our beef with the French is almost entirely the fault of one supremely arrogant man: Charles DeGaulle. Churchill did not like him and FDR hated him. Now most Frenchmen try to emulate him.
And you drive a Renault, right? :-)
