Michael Laris:

The I-95 Corridor Coalition, which represents transportation officials from 16 states and the District of Columbia, applied for a federal grant last month to test the idea.
 Officials would stitch together the policies and technologies needed to count the miles driven by 50 recruits from each of the four states, including state legislators, transportation officials or other willing guinea pigs. They would send out “faux invoices” monthly. And they would collect the data that legislatures — and the driving public — would require to decide if the change makes sense.
 Although California plans to launch a pilot in July, also with fake invoices, and Oregon has had success with a volunteer program collecting actual cash, the concept is not particularly well known — or well loved across the country.
