On vehicle taxes . . .
Like zahc wrote, TX is charging EVs extra annual registration fees since they're not paying any gasoline tax. Other states are trying GPS tracking and having vehicle owners pay by the mile . . . but the thought of .gov monitoring their every move via GPS tracking doesn't set very well with most folks.
Some people have converted their vehicles to dual-fuel, at least if they live in an area plumbed for natural gas. If they have a hookup (which includes a high pressure compressor) in their garage, they're SUPPOSED to have a meter on that so they can pay motor vehicle taxes, but I understand few do. Some folks with access to used cooking oil (restaurant owners?) have their own systems to filter/purify it for use as biodiesel, but again, if they keep their mouths shut they don't pay fuel taxes. I DID hear about .gov going after some high school or college students who adjusted a diesel car of some sort to run on processed cooking oil - even though it was for some sort of a school-related project, .gov was still upset about them for not paying fuel taxes.
I remember reading about someone who either had or was working on some sort of a filter or process to remove coloring from agricultural fuels so they could undetectably be used in road vehicles, and .gov was unhappy and "investigating." Don't remember seeing any follow up.
Oh, and NOT ALL GAS TAXES ARE USED FOR THE ROADS. In various places, the road fund is routinely pirated for "other, more pressing needs."
