Note to French scientists: Those who can, do. Those who cannot do, teach. Those who can neither do nor teach, criticize. One makes vinegar, not wine, with sour grapes. If you wish to be taken seriously, show us your innovations; otherwise please remain by the roadside. Your racing machines are excellent...your road vehicles, not so excellent. My 2004 Prius has over 90,000 trouble-free miles at an average fuel economy of about 55 mpg. I never owned a French vehicle that could come close to that.
