Well, this is going to fall off a cliff, because as of 2020 Ohio charges an extra $200 per year on the registration fee for a BEV or plug-in Hybrid. (Standard / non-Plugin Hybrids are an extra $100/yr.)
My dad had been super excited to trade his Cadillac ATS for a Cadillac ELR (PHEV)... then was rudely surprised by this extra $200 fee at registration. In order to "make up" this cost in fuel taxes (which is Ohio's justification for adding this fee, lost gas tax revenue), he'd have to drive something like 18k miles per year. He drives more like 7000-8000 (his daily commute is maybe 15 miles total, which is part of why he was so jazzed to go for a PHEV and "almost never need to buy gas again").
I'm guessing the Ohio legislature is all Republican?
Gotta protect the fossil fuel industry status quo in our crusade to get back to the 1950s.
The correct answer to the question of "how do we make up lost tax revenue from lack of gasoline sales" is to increase the tax on gasoline by a few cents a gallon, thus maintaining tax revenue while providing additional incentive to buy a BEV when it's time to replace your car.
