The dip in gasoline use in 2020 was due to the reduction in personal vehicle use during the initial phases of the coronavirus pandemic. However the long term drop in per person gasoline use is likely due to fuel economy and greenhouse gas standards that have made gasoline vehicles more efficient over the prior decades.
