The gas tax is a perfect method to charge for the impact of motor vehicles. Heavier, gas-guzzling vehicles pay more, while more fuel-efficient vehicles pay less. Electric cars pay nothing, serving as an incentive to switch away from fossil fuels. And there is no complex technology required to collect the gas tax.
So why all the push for VMT (vehicle-mile traveled) taxation? Perhaps because private vendors will make a fortune:
There is also growing concern about the cost of the program. OReGO vendors will collect up to 40 cents of every dollar drivers are charged, and green car drivers could be in for some serious sticker shock every month.
If the 40% figure is correct, then that is quite a scam. Almost half the money would go to private firms, instead of paying for road maintenance or other transportation programs.
