When you buy gas at the pump, there’s a little sticker there that you might not ever have noticed. It says how much you’ll be charged for our state’s gas tax.

The money, for the most part, goes back into our roads. The idea is we all drive on them so we all pitch in for upkeep. But, now that so many hybrid and electric vehicles are on the road, the math doesn’t quite add up.

So the state of Oregon has opted for an alternative. They’ve tested out a pilot program with the catchy name Ore-GO to find out if drivers will pay cents per mile they drive instead of paying a gas tax.

While they were studying Law and Sustainability at ASU’s Sandra Day O’Connor College of Law recent grads Courtney Moran and Casey Ball studied Oregon’s pilot program to find out how well it worked, and if it’s too radical for the rest of the country to ever catch on.

I sat down with them both recently to talk more about this, and I asked them, first, to explain to us how exactly this program works.
