Here in California, 20k miles of driving at 30mpg (so, highway only, which is of course unrealistically high) is $600 in gasoline taxes per year, with California state and local taxes at $0.612/gal; meanwhile, the EV registration gas tax makeup fee is $118/yr, which is equivalent to 192 gallons per year of tax, which at 30mpg is merely 6k miles, not 20k. California average miles driven is estimated at 11k.

So: the EV loophole is costing the state half of the road maintenance tax budgeted for road wear in subsidies paid to EV drivers, assuming that all gas vehicles get 30mpg at all times. I don’t expect that gap to last much longer now the Federal government is openly hostile to the state. Hooray for silver linings, I guess.
