Since December, John Duncan's daily commute from Wilsonville to Portland has been like something from a sci-fi movie.

He's a solitary eco-driver -- the first and only owner of

in Oregon -- who knows his day of reckoning is just down the road.

"I figured the state would find a way to get the gas taxes that I'm no longer paying," said the

theater arts teacher. "But I'm hearing about a new tax that will be something like $1.43 a mile. Really? Wow!"

Yep. Wow! Of course, that's not exactly accurate. Oregon lawmakers are actually considering a road-usage charge of 1.43 cents -- not dollars -- per mile for drivers of electric and plug-in hybrid vehicles.

Among those drivers, the "EV fee,"

, is sparking all kinds of confusion and concern as it cruises through the Legislature.

Will they need to buy an expensive gizmo so the state can track mileage? (No.) Can the government really repossess someone's plug-in Prius for not paying? (Yes.) Is the tax fair? (Depends on who you talk to.)

Opponents worry the state is pushing buyers away from nonpolluting electric vehicles just as they are beginning to build momentum. John Christian, chair of the

, said he understands the need for the fee. But he thinks lawmakers should wait until the number of electric vehicles on the road hits at least 25 percent and greenhouse gas emissions come down.

"What's the message they're sending?" he said. "With one hand, they're offering a tax rebate to get you to buy an electric car. With the other, they're proposing a new tax. It looks like money-grubbing."

But with everyone else paying a 30-cent-per-gallon gas tax to build and repair roads, it would be unfair not to move forward with the legislation, said

.

"It's the backbone of our transportation infrastructure: Users pay," said Starr, a key supporter of the bill. "This is not about penalizing electric vehicle owners. But why should they get a tax-free ride?"

Starr also noted that EV owners benefit from publicly-funded charging stations popping up in Oregon cities and along the Interstate 5 corridor. On Friday, U.S. Transportation Secretary Ray LaHood announced a $2 million federal grant to build 20 more stations in the Portland area, allowing electric vehicle drivers to travel longer distances.

In Salem, the House Transportation Committee has voted in favor of the bill, which applies to electric and plug-in hybrid vehicles starting with 2014 models. It's awaiting a hearing by the Revenue Committee.

Oregon, the first state in the union to charge a gas tax for road maintenance in 1919, is one of three states -- along with Washington and Texas -- exploring different ways to bring electric vehicles into the revenue mix.

Since the first hybrids began appearing on roads a decade ago, Oregon has worked more than any other state to study how new technology and improving gas mileage could shrink revenue, said James Whitty, an ODOT alternative-funding manager.

Less than 1,000 of Oregon's 3.2 million passenger vehicles are currently plug-in hybrid or electric. By 2021, however, the number is expected to spike to 75,000, said Whitty.

Under HB 2328, an EV owner would pay about $172 a year for a car driven 12,000 miles.

"We're talking roughly the same amount as the gas tax paid on a vehicle that gets (the average mileage of) 21 mpg," Whitty said.

Sounds reasonable, said Gary Graunke, a longtime hybrid driver who expects to join Duncan as the owner of a 100-miles-per-charge LEAF next week. But Graunke is struggling with other parts of the bill. A provision allowing the state to seize and auction vehicles belonging to those who don't pay is "overly draconian," he said.

"It's also not clear if they'll make me buy some $500 gadget for my car to track the miles," Graunke said. "Our vehicles are already more expensive to buy."

Before $9,000 in federal and state tax credits, the price of a 2011 Nissan LEAF starts at about $32,000. By comparison, a similar-size Toyota Corolla starts at $15,250.

ODOT officials said they are developing technology –ranging from smartphone apps to programs utilizing GPS systems built into the electric glow of EV dashboards – to report mileage without extra costs. Drivers could also receive refunds for miles driven outside Oregon.

Even if it's not $1.43, Duncan thinks the proposed tax is "punitive." He said he pays only a penny per mile in gas taxes when he drives his other car -- a 1997 Saturn SL. His neighbor pays even less in his fossil-fueled Mini Cooper.

Duncan prefers the proposal that Washington lawmakers are considering -- a flat, easy-to-collect $100 annual fee for electric vehicle owners.

After years of Oregon working with the federal government, power companies and automakers to get people into electric vehicles, Duncan said, "members of the Legislature have turned around and tried to do exactly the opposite."
