While I agree with the principle of this, the rate is clearly excessive. The current Federal gas tax is 18.4 cents per gallon, so the rate that they are proposing is the equivalent of 1,087 gallons per year. The average new cars efficiency in the USA is about 28.5 mpg, so this is a
flat tax that taxes people as if they drive nearly 29,000 miles per year. In fact the average American driver goes just short of 13,500 miles per year. Furthermore EVs generally are driven fewer miles per year (since many families with two cars will use their ICE car for longer trips due to range anxiety), and internet numbers (your milage may vary) suggest that EVs average around 11,000 miles per year. So this is a flat tax, without regard for individual road usage (and resulting wear), that hits EVs users at more than 2.5 times the rate that the Federal gas tax hits the average gasoline car user.
Notwithstanding the contrary evidence from the tariffs, I believe that some people in the current administration are capable of doing math. As a result I think that it's fair to conclude that this is not just an attempt to make EV owners pay their share but is in fact a punitive attack on cleaner vehicles that don't buy their energy from Trumps donors.
