So tax the zero-emission electric vehicles for using coal energy in certain areas (over which they have no control), instead of the actual coal companies that produce that dirty energy? That seems quite backwards to me.
Tax the coal companies and force them to either convert to renewable energy production, so then the electric vehicles can be 100% clean, or to force them to shut down (and be replaced by renewable competitors).
Taxing electric vehicles just as much if not more than gas-powered vehicles because they use coal energy right now is complete nonsense. At least electric vehicles try to solve one half of the problem. Taxing them like that would put the breaks on both sides of the reform. Let's solve both problems in parallel instead of putting the breaks on both (not forcing coal companies to die/convert faster and also continuing to use gas-powered cars).
