Drivers of alternative-fuel vehicles, with their distinctive blue license plates, are becoming targets of angry taxpayers' road wrath. Writer William Least Heat Moon says he gets a clear idea about how other drivers feel, seeing more and more of his fellow travelers' “middle digit opinion.” Randy Jenkins of Glendale, AZ, has experienced similar boorishness on the road. He bought his electric car a year ago. Since September, when the alternative-fuel program's costs came to light, he has noticed an increase in drivers cutting him off or giving him angry stares. "There's a lot of one-finger saluting going on," said Jenkins, who runs a payroll service. Perhaps the worst result of the alternative-fuel scandal is the stigma it has put on vehicles that don't pollute the air, such as Jenkins' Solectria, which he says he bought because his wife doesn't like getting gas. "I haven't gotten a dime out of the state of Arizona for this," he said. "I paid twice the price for a car, now to have my neighbors mad at me. ... And they don't know what motivated me to buy.”
