Gas prices are falling nationwide. A survey conducted by AAA this week reveals the average price at pumps across the U.S. has dropped below $3. California has experienced a bigger price drop than any other state, with motorists paying about 40 cents less per gallon this month compared to last month. The average national price has been dropping for over 45 consecutive days. Falling oil prices have been caused by an array of factors, including a significant increase in crude production on a global scale, the end of the peak, summer driving season, and more fuel-efficient cars on the road.
