5.09 - lol, ok maybe in the rural parts of the state or something. In L.A. it's $5.50 at the very cheapest stations (read: go out of your way and maybe waste 10 minutes waiting, then wait in line to pay cash) and even Bakersfield is about $5.25 minimum. $5.60-5.75 is what I see on most normal stations.
The refining regulations are so great that they have succeeded in forcing nearly every refinery here to close now, so I guess gas prices can just go asymptotic, since California only allows this special unicorn gas, and I doubt any of these oil companies are going to open a new refinery in Arizona to make this special formulation, when they're closing the refineries here that used to make it. Maybe Sacramento can buy the closed refineries and restart them at great taxpayer expense and create our version of state-owned oil companies, except instead of printing money they'll be printing debt.
