(AOL Autos) A California transportation agency recently proposed what could become the most unpopular tax of all time: A tax for simply driving your car.

The Metropolitan Transportation Commission of San Francisco is behind the idea and has said that the tax would work by installing GPS units into cars to track the miles that they travel. The vehicle owners would then be charged accordingly, with low-income drivers exempted.

The hope is that a VMT (vehicle miles traveled) tax would cut down on pollution and traffic congestion, while raising funds for things like road construction and surface repair.
