Last July, the Oregon Department of Transportation started a pilot program called OReGO to test the idea of a state tax on miles driven—a tax in which Oregonians driving fuel-efficient vehicles would pay more than they do in gas tax while those driving fuel-inefficient vehicles would pay less ("Paying by the Mile," WW, June 30, 2015). The idea was to replace the state gas tax, which is in long-term decline. Jim Whitty, who spent more than a decade researching and marketing OReGO around the world on ODOT money, told WW at the time that "guilt" might be the sole incentive for owners of fuel-efficient cars to sign up for OReGO. He hoped 5,000 Oregonians would sign up for a trial run of the program, paying per mile traveled and receiving a credit for gas taxes paid. But apparently, guilt hasn't been enough. As of June 1, only 891 people were enrolled in OReGO, according to ODOT's Michelle Godfrey, and all four businesses that enrolled also happen to be registered as contractors with ODOT. "Our current numbers are more than adequate to fully test the OReGO system," Godfrey says. Meanwhile, Whitty retired from ODOT to join D'Artagnan Consulting, an ODOT contractor. Agency rules bar him from doing business with ODOT for 12 months.
