Gas prices highest in 6 years as panic-buying prolongs shortages

More than 10,000 gas stations remained without fuel Tuesday as states in the Southeast slowly recover from a ransomware attack that crippled the biggest U.S. pipeline earlier this month.

Although Colonial Pipeline resumed operations five days ago, gas prices have continued to edge up after alarmed motorists mobbed pumps following the hack and ahead of the Memorial Day holiday that marks the traditional start of the summer driving season. Patrick De Haan, head of petroleum analysis at GasBuddy, which compiles data on gas stations using "crowdsourced" reports from consumers, blames most of the empty pumps and price spikes on an overreaction by consumers.
