Obama administration floats draft plan to tax cars by the mile

The Obama administration has floated a transportation authorization bill that would require the study and implementation of a plan to tax automobile drivers based on how many miles they drive.
The plan is a part of the administration's Transportation Opportunities Act, an undated draft of which was obtained this week by Transportation Weekly.   The White House, however, said the bill is only an early draft that was not formally circulated within the administration.***
News of the draft follows a March Congressional Budget Office report that supported the idea of taxing drivers based on miles driven.  Among other things, CBO suggested that a vehicle miles traveled (VMT) tax could be tracked by installing electronic equipment on each car to determine how many miles were driven; payment could take place electronically at filling stations.   link
