As part of a pilot program by California to reduce pollution and increase the popularity of gas-free vehicles, Anaheim is offering free use of 10 electric cars in some of its lower-income neighborhoods. The golf cart-like cars are available to people who have a valid driver’s license and a decent driving record. With a maximum speed of 35 miles per hour, the cars are suited mainly for quick neighborhood trips, which account for about 85 percent of pollution caused by cars. Gabby Castelan, an Anaheim resident, said, “We use them all the time. We go everywhere — to pick up my daughter at school, to the post office, to get lunch.”
