The national average for a gallon of gas has decreased by four cents to $3.50 since last week, according to recent data. This decline is attributed to low demand for gasoline, potentially influenced by high summer temperatures.

"The arrival of summer used to signal the start of a robust driving season, but that has not been the case recently," said Andrew Gross, AAA spokesperson. "We know that a record number of travelers were forecast to hit the highways for the July 4th holiday, but since then, they appear to be staying off the road, and the recent scorching heat is possibly to blame. Maybe things will pick up soon."
