NBC News updated its AAA gasoline tracker on October 31. The national average was still above $4 a gallon, more than 40 percent higher than when the Iran war began and more than $1 a gallon above that starting point. California, Hawaii, Nevada and Washington averaged at least $5. Georgia, North Carolina and Texas were the cheapest states in the write-up, which did not give their dollar prices. Since mid-May, the national average has eased by around 20 cents, so October 31 is not a fresh unbroken surge.
NBC cited a Brown University estimate that the war-period gasoline increase has cost Americans more than $70 billion. That is a national total, not one driver's receipt. The piece also said jet-fuel prices have surged and airlines have raised fares, without publishing a new fare sheet. An AAA average is not the price at every station.
Did the October 31 update raise every driver's gasoline price? No. It shows a national average still above $4, four states at $5 or more, and a roughly 20-cent easing since mid-May.
