In BC it is, supposedly, tax neutral. While I paid more at the pump, my tax rate fell. I could either pay the carbon tax or keep the money and buy an EV. The low income GST and working income tax benefits offset the cost for the poorest. But only if they file taxes. so they get screwed.  I think toll roads, toll bridges and other user pay fees are the most regressive of taxes. Pretty soon the only people who can drive are the uber-rich and any company who can pass the costs onto the rest of us. We should be free to drive any darn car we want down any road!
