Think it's all going to go Mad Max/feral fairly soon. Been expecting this since the 1980's not too long after the trial run during oil crisis of 1970's which was whole point of the Mad Max movies that followed not long after.
We're like one bombing run from losing all petroleum supplies from Middle East followed by gas rationing via digital id/social credit etc. Plus everyone's going to have to duke it out with the new arrivals over things like bicycles.
