But aren't cars in places like Europe and Japan more fuel econmical that US cars? So no one is arguing that one has to stop use electricity or motorised transportation. But if you car can travel further on the same amount of fuel then it is better for the enviroment. Sure one could argue that electric cars are just shifting the emissions to the power planets rather than from an Internal Combustion Enginge(ICE), but surely some of that can be mitigated by adopting greener power generation such as Wind/Tidal/Solar/Geothermal/Hydro to name just a few.
It costs the companies a lot of money to research, develop and market fuel economic, hybrid or electric cars. That's the only reason. And in the US it's especially expensive to market such a change, as it's also an attack on the citizen's freedoms if they are denied driving fuel
ineffective cars. That's like denying them to drink alcohol, or denying them to have guns.
