WASHINGTON _ Take the little black box that's about the size of a fist. Plug it into the data port that in most cars sits under the dashboard. It'll record how far your car is traveling.
Using that information as a potential tool for raising taxes to fund infrastructure is an idea that Democrats and Republicans are seriously discussing.
In Oregon, reading the box is how the state calculates a driver's road usage, which in turn is used to figure a tax on miles traveled. This sort of tax, if expanded nationwide, could be a big way governments pay for all those infrastructure improvements that the White House and Congress are striving to fund.
