From the Mail: "A racing car that is powered by chocolate, guided by a carrot steering wheel and has bodywork made from potatoes, was unveiled in Britain today."
"The car meets all the Formula 3 racing standards except for its biodiesel engine which is configured to run on fuel derived from waste chocolate and vegetable oil. Formula 3 cars currently cannot use biodiesel."
I do see a problem here: chocolate is already freaking expensive enough. I don't need car drivers sending the prices up higher. Otherwise, I'll have to find a cheaper vice, like smoking.
