Only us old geezers remember the long lines, every other day fill-ups, and the wasted time of the early '70's, and yes the increase in price too. Not worth my time to research the price increase in percentage terms as I really don't care as much about price as availability, thankfully we're not dependent on the middle east for our domestic supply any longer. I was reminded of this a few years ago when we were almost stranded in Maggie Valley,NC when Russian hackers shut down a pipeline from the Gulf that supplied a good part of the SE with refined product. All flow valving had been converted to electro-mechanical switching controlled by computers and all the old geezers that had a clue how to bypass the new valving had retired, so the pipeline company payed the ransomware hackers. There are only 4 gas stations in Maggie Valley, tourist town with mainly hostelry, restaurants, and curio shops. Fortunately for us the owner of our Air BNB had just seen a tanker at a Citgo station, so we hustled on down there and filled up. You hear lip service about how our critical infrastructure is vulnerable to foreign adversaries, but the solution seems to be all about "hardening" our critical systems against computer attack. It would be expensive to install and train the personel but I believe we need MECHANICAL redundant systems at all our critical points, a mechanical switch that could actually be thrown by a human at a substation or an actual valve that could be turned by a human at our domestic water supply station, but that's just me, since I'm old my only worries are for my children and grandchildren and their world.
