This adds cost. It also means there are a limited number of refineries who produce these formulas which reduces competition. It means gasoline can't be brought in from across state lines, except in emergencies with the governor's order. If you have a couple of refineries down due to problems, then the supply tightens quickly in ways that don't happen in other states.
Californians have decided its worth the cost and loss of flexibility, and obviously live with the consequences good and bad.
To an extent Californians have. We’ve had a Democrat Legislature for the 50-75 years, with one year or so exception.
Thus about 47% of the state’s citizens have no say in what takes place.
These refinery issues are something we’ve had for decades. Granted the one or two refineries with problems now, aren’t something that has been traditional 100% of the time.
