Same as 1973 - I was driving down the West Coast in Sept 73 in a BMW 2002 from Vancouver to San Diego and back x-country to Calgary. Ran into gas shortages and closed stations all the way thru Oregon and N. Calif. Learned very quickly to buy gas often, when ever a station was open.
Lots of signs to pay in advance then also, to avoid "drive-aways".
This will pass, but makes for good internet chatter in the meantime.
