If you think the knuckleheads that “roll coal,” key cars, cut off electric cars etc. have a clue about taxes on EV’s you are grossly overestimating their knowledge. Even most educated Arizonans probably would be surprised to hear about the tax break. I suspect seeing single occupant cars with blue plates in the carpool lane is the main aggravation.
For many older adults who hate our blue plates, you can bet it goes back to the alt fuels scam in 2000-2001. Poor ignorant Gov. “Propane” Jane Hull. Her decision to sign that legislation was the dumbest decision of her lengthy public life and it wasn’t even a payoff for her friends. It still annoys me that my next door neighbor at the time got at least $20,000 back from the State on his new Ford Expedition purchase after ”converting” it to a bi-fuel vehicle courtesy of a tiny propane tank that he never filled!
