did you read the byline? "gasoline demand in the U.S. plummeting and oil inventories surging" Prices dropped in 2020 because demand dropped while supply increased. Trump asked Russia and Saudi Arabia to decrease production so American companies didn't take gigantic losses and possibly go out of business. If those companies went out of business then when demand increased there would not be enough production to meet demand, thus increasing prices. But then we got Biden as president, and government limited production anyway, thus the high gas prices now.
