NPR's Glinton says, "under fuel-economy rules announced by the White House this summer, cars will have to get an average of 54.5 miles per gallon by 2025 - nearly double the current average. Reaching that goal will take not only feats of engineering but also changing how Americans think about their cars and how they drive them."
Glinton notes that electric cars will require change in consumer habits which so far has not proved to be what consumers want.
"Not that much has changed with electric cars in more than a hundred years. Casey says if they're to be widely adopted, it's drivers themselves - and their habits - that will need to change."
