I don't think people fully understand yet the potential of self driving cars and AI traffic management to massively increase the density and flow rates on highways. I'm fairly certain it will be quite easy to double the density while simultaneously quadrupling the existing flow rates - with much better improvements coming later. Which means right now we are at the "peak delay" point for the next hundred years or so.
