Perhaps, but I am assuming that this is based on the idea that older cars that consume higher rates of fuel will be off the road and will be replaced with more efficient cars, hybrids and electric cars. This will be true in the U.S., Canada and Europe....
But.....the middle class is rising in China, India, Asia and other parts of the developing world.
After the rising middle class buy a home, eat better food and buy a few new clothes they want a new car.
Hybrids and Electric cars are more expensive than a standard gas engine. So they will buy a gas or diesel car.
Whatever improvements we make in the West will be offset by gains made elsewhere around the world.
Just my personal observations.............
