Huge military investment in oil-producing countries and regions.
Building and transport codes built around the needs and technologies of dinosaur burners.
Lack of significant restrictions on emissions.
I don't think you're gonna get back the sum of the decades of subsidies of various sorts that cut the cost of technology developments.
(yes, I know they aren't really "dinosaur" burners but alge burners)
And that's just the stuff that's out in the open.
All of that subsidizes any ICE car.
I’ve attempted to research this issue before, but the information I’ve found is very poor. A common problem is grossly inflated figures that include deductions that apply to every business.
Also, I haven’t found a resource that accounts for the full tax load on oil. For example, electrics are not subject to the sizable per-gallon taxes on gas and diesel, which means ICE cars are subsidizing electric’s road usage.
