OReGO -- the first pay-by-the-mile program in the U.S.
Oregon’s Department of Transportation has been working on it for 15 years as a way to eventually replace the gas tax, which has been flat due to an influx of high mileage vehicles and people driving less.
Right now the program is voluntary and being capped at 5,000 participants, but an ODOT official told Fox News the ultimate goal is to make it mandatory and change the way states pay for roads -- forever.
