I had no idea this had been solved. Why don't all manufacturers do this?
It might not be totally solved.
If, for the sake of an extreme example, you're filling your car in some far flung and yet beautiful East African town then the pump nozzles may not be uniform as they are in Europe and as such the Ford solution might prove to more of a handicap than a benefit. This, however, does not represent the more usual market for new Fords.
But Ford has done what Ford does best, which is to provide an elegant and cost effective solution to something which, although, not quite a cliffhanger, is otherwise still possibly substantially inconvenient and costly to its customers who otherwise might use the wrong fuel.
Ford was the butt of much motoring press baiting and general slagging-off during the 1980s. Possibly deservedly. That's not the point of this post, however. When Ford gets something right it gets it very very right indeed.
Even during the 1980s a certain UK motoring glossy described the door aspheric door mirrors of the Ford Sierra as 'the best mirrors in the business, period.' OK, they derided everything else about the car.
But look at the MkI Focus in 1998. Even now it's handling is up with the finest of its kind.
Current Mondeo, well, I'd take a new one over a new BMW or Audi simply to be different to the crowd.
