AFAIK EV owners pay no road tax through fuel taxation and they even get tax breaks on purchase and registration? Why is WVO any different?

There are specific laws against using fuels not intended for vehicle use. Running your car on ag fuel is purposely skirting taxation. I don't run my car on WVO to skirt taxes, there's just no mechanism to pay taxes on it. How is that my fault? It's the government's job to figure out how to tax me.

Is there a road tax on propane for road use?

Does anyone know what the road tax rate is on biodiesel from Arco or a similar commercial source?
