The Feds are rolling back previously announced CAFE fuel economy standards, and the nation's automakers are cheering them on.   During this episode, we ask hard questions about the recent CAFE rollback. Automakers once pledged ambitious fuel-economy targets; now a lower bar opens the door to thirstier engines and higher pump bills. We weigh short-term sales against long-term competitiveness as global markets sprint toward hybrids and EVs. What does “choice” really mean if it nudges buyers toward pricier drivetrains and trims while public health and fuel costs foot the bill?
