Whereas many years ago 30 MPG was common for many ICE cars , and through regulations and public pressure many cars now do 45-60 MPG if the manufacturers figures are to be believed . If the average driver is only doing the same yearly mileage then there must be a reduced tax revenue there which could be addressed by , oh ! lets see a PPM tax on ICE vehicles to make up the shortfall, from what they normally would have contributed. After all fairs fair.
That would stop the mass migration back to ICE cars if some of the social media reports are correct and the governments mandate of EV adoption can get back on track. I put it to the house!
