We do not have state income tax. This is to make up for gas tax of .21 cents a gallon charged per gallon by the state. I only drive the approximately 1100 miles per year, running errands, ect... so ev owners are being charged for 952 gallons of gas a year. Unfair taxation. I have combustion vehicles (3) and pay at the pump. Ev tax $200 plus $65. Hybrid tax $100 plus $65.
I reckon it's *always* possible to feel justified, when complaining about inequitable taxation!
I'd say that $200/yr, per registered vehicle, is a pretty low price to pay for the privilege of having a state-maintained roading network. But ... I have no idea what fraction of the roads in Tennessee are state-maintained! If you rarely drive on state-maintained roads, then ... I suppose you might hope for a future in which "big brother" is monitoring the roads on which you are driving, charging you per mile for this privilege, and then sloshing your per-mile dosh into whatever kitty (city, county, state, federal; for-profit toll-road operator) is most appropriate. Yikes -- that'd be scary IMHO. And really really complicated! I'm all in favour of keeping it simple when it comes to taxation -- because people will *always* complain about unfairness, no matter how the taxes are assessed!
You might be interested to know that New Zealand, where I now reside (I'm a dual NZ/US citizen), has recently enacted legislation charging EV owners $78/1000km. That's about USD $30 per 1000 miles. So I guess you'd like that scheme, since you drive your EV so little each year! (Good on you, by the way, as *every* mile in *any* vehicle has a non-trivial carbon-cost!) The owners of PHEVs in NZ are assessed $39/1000km, no matter whether they're being "fueled" mostly from the wall socket or mostly from petrol. Yeah it's unfair but what's the reasonable alternative -- aside from the "big brother" style of electronic monitoring... which I suppose you might be able to adequately sugar-coat for the anti-gummint crowd by putting a private for-profit firm in charge of collecting the revenue, as has been proposed here in NZ and I suspect elsewhere on this comment-thread!
The state of Victoria in Australia recently lost a constitutional challenge to the *very* unpopular $25/1000km road-user charge on EVs which started in 2021.

Obviously: owners of vehicles that aren't driven very much in a year would greatly prefer to support the roads based on how much they drive.
Owners of vehicles that are driven much more than the fleet-average number of miles in a year would greatly prefer to pay yearly by the vehicle they register.
Owners who rarely (if ever) drive on state-maintained roads will scream bloody-murder at *any* charge.
Excise tax on fuels must be increased, as the fleet fuel-efficiency improves -- unless you vote in a government which promises it will build and maintain roads "faster cheaper and better".
Having poorly-maintained roads is also deeply unpopular.
Bottom line: people will complain about any taxation!
