The article suggests it will take 2-3 days for gas stations to run dry.
That strikes me as overly optimistic.
The city of Phoenix gets nearly all its gasoline via a pipeline connected in Tucson to another pipeline from El Paso.
About 10 years ago, that pipeline from Tucson sprang a leak and was inop for a couple of weeks while being repaired, and all gasoline/diesel fuel had to be trucked from Tucson.
It didn’t take 2-3 days; gas stations started running dry in hours.
Stations that had gas had long lines, just like in the ‘70s.
There were three stations on the corner nearest to where I lived. One of them generally had gas, but usually by the time one of the “empties” got restocked, the one that had gas was either “out” or darned-near out.
After Camille struck MS in '69 we had no power in the area for weeks. There was only one station that had a back up generator. It led north out of Gulfport on Hwy. 49. The line there was three miles long. The owner decided to raise the price to $1.00/gal since he was the only game in town.
The Harrison Co. Sheriff came in and arrested the jackass for gouging, took him to jail and took over operation of the station.
Point here is that loss of power has an IMMEDIATE effect in all sectors whereas, truck stoppage gives folks a little bit of time to do something even though it is a very short amount of time.
What you describe is a perfect example of what will happen if an emergency happens like this.
People panic. There was a 3 day supply but due to panic, everyone was rushing out to top off their tanks and caused a panic which led to more people rushing out to get gas which kept a bad situation worse.
