Case in point - much of the world has a 100% tax on gasoline and diesel. In effect, they are forcing their consumers to pay 200% of world prices for motor vehicle fuels. We are buying the excess supply that they don't consume at a lower price than we would if that 100% tax did not exist. Their hair shirt policies are benefiting us at their expense, just as any hair shirt policies we adopt will benefit the rest of the world, at our expense.
The simple truth is that we don’t begin to have the necessary alternative sources of energy to replace oil regardless if every car in the country were electric or not. If they were all electric we’d be burning oil to generate the electricity needed to power them all. Electricity is simply a means to move energy - it isn’t a source of energy. Oil is a source of energy and therefore not even remotely the same thing. Electric cars do not negate the need for oil energy.
