I'm a fan of subsidizing green electricity generation (and I include nuclear power as green) and electric cars with a progressively increasing tax on gasoline.

I'm a fan of subsidizing green electricity generation (and I include nuclear power as green) and electric cars with a progressively increasing tax on gasoline. Most (not all of course) of this nation's towns have been engineered around roads and cars. You can't just add a light rail or a subway and expect instant adoption. You can, however, gradually change the nature of the cars and the fuel that powers them. I would expect such a plan to go absolutely nowhere for the same reasons you outline above.
