"tolls for roads the taxpayer has already paid for, on the fabricated premise that electric cars don't pay road tax"
All very well, except your road tax has sod all to do with roads. Road maintenance is paid for by local taxes by and large, your "road tax" (vehicle excise duty) goes to a government fund. Toll roads would be a good way of funding roads directly, and making those who use them most pay relatively more. Don't expect our glorious leaders to cut excise duty on cars to compensate, of course.
