Are you sure they are not?

Keep in mind most of the Europe fuel cost is tax. Pretty easy for the governments to apply the same to other fuels as well.
And where are the 100 mile per gallon cars? The Electric cars? The Fuel Cell cars?
Basically this is various on a theme, not a change from the basic equation of Oil based power.
Like the Prius etc these are still looking like rich man toys, not viable alternative to Oil based power.
