The tax isn’t $1.29, motor fuel is included now in “Carbon Credits” needing to be purchased so it floats, and it’s probably more like $.20-.30/gallon. The other portion of the increase here is mainly due to CARBs summer formulations and the ability to jack the price via the excuse of the Exxon fire a couple weeks back.
It’s up about $1.00 here in the east bay area.
Don’t forget also that in CA the dog excrement sucking douchebags in the legislature get sales tax on top of their fixed tax in the price of gasoline so $4+ dollar gasoline will always have them peeing their pants for the windfall which helps mask their inability to refrain from blowing our money on worthless crap like taking care of non citizens and 200+ mph trains that will be under construction for 75 years and go 90 mph tops...
Combine that with their special recipe requirements that complicate bringing in gasoline from other locations and you get price spike over the last month.
There was a Democrat super majority that passed a $1 plus a gallon additional tax that can be implemented when they think the time was right. Not about tax credits, it was a Dem super majority using their numbers to tax EVERYONE including the poor.
