Looking at the table above and your linked article the numbers don't add up. My gas guzzler has an 18 gallon tank. Looking at the taxes we see:

1. CA State Tax - $9.72

2. Fed. Excise - $3.31

6. Local Taxes - ($2.00/gal * .037) - $1.33

Which adds up to $14.36 in taxes every time I pay for a full tank. I use about a tank a week. So, I buy 52 tanks of gas a year. This works out to $746.72. I also pay car registration of ~$300 a year.

From the article you're only paying a one-time fee of $100. The registration fee is also capped $175 first year. My total tax burden (gas taxes + reg) is $1,046.72 and yours is only $275 for the first year, $175 after.

I intentionally left out the low carbon programs in my calculation to make a fair comparison. The taxes above that are paid are required to fund roads, schools, etc. None of which you're paying on your EV. You're saving $871.72 from not paying for these things.

Also, I asked chat GPT how much it costs to charge an electric vehicle at home. It gave me the formula: 60 kWh x $0.20/kWh = $12. So this would be $624/year. So assuming gas w/o taxes @ $2/gal my gas guzzler is costing me $1872 a year. $1248 more than your EV. This is some good cost savings.

So including the taxes above you are not paying and your cheaper charge rate, your total cost savings is around $2,119.72. This is a pretty decent cost savings.

So you're correct, EV vs. gas is definitely cheaper. But, the point that I'm making is that nearly 40% of your cost savings accrues from not paying taxes on necessary things like roads and schools. The cost effectiveness of EV's has more to do with tax policy than the underlying efficiency gains technology. Ideally they will become cheaper over time, but the significant cost of taxes to fund the government programs we need is going to remain.
