Here is an interesting fact that I read in the latest edition of the BBC Wildlife magazine which I thought summed up the car industry's attitude to fuel.
"US cars average 20.8 mpg. The Model T Ford managed 25mpg, the Ford Explorer SUV does 16mpg".
That's nearly 100 years of innovation! But, I can remotely eject 15 cupholders and flip down 5 TV screens from my car key fob.
