The main reason the VMT fee is being promoted in most circles is because the gas tax, currently 18.4-cents per gallon, by not being raised regularly (last time was in 1993 by 4.3 cents) or indexed for inflation, has shown itself to be an unsustainable form of transportation revenue. Noel Popwell, "a freelance writer and a revenue analyst with New Jersey state government", argues that aside from being sustainable revenue generator, the fee should be considered for five reasons:
Popwell writes that the GAO found that all states "reported strong support for federal action to move toward this new financing method. And more than half cited the administrative costs of implementing the system as a serious barrier to moving ahead."
Popwell doesn't ask President Obama to support VMT fees per se, rather, he wants the administration to drop "its opposition to the concept and provid(e) the resources needed to fund ongoing state pilot programs, and start new ones".
On a related note, Ore. Gov. John Kitzhaber signed SB 810 on August 14, creating the nation's first VMT fee. However, it it is only available for up to 5,000 motorists who will pay a VMT fee of 1.5-cents for every mile they drive instead of the 30-cent state fuel excise tax.
New Jersey, the state where Popwell works as a revenue analyst, considered legislation to implement a VMT fee this year. Instead, the legislature opted to charge an additional $50 flat registration fee for EVs - regardless of the amount of miles the vehicle is driven. How smart is that?
