Vox Baby on Fuel Economy and Safety:
Karen Lundegaard has an intereting article today in the Wall Street Journal about new thinking about fuel economy and safety.
The story presents a graph from the EPA showing fuel economy over time for cars, trucks, and then their combination. It makes the point well from an earlier discussion of the CAFE standards (here, here, and here). Even though fuel economy per vehicle may have been flat to increasing for both cars and trucks, the shift of more drivers into the less efficient trucks has caused the overall fuel efficiency to fall.
