TRENTON, N.J. --- In response to soaring gasoline prices, New Jersey Gov. Jon Corzine is urging state legislators to approve a pilot program that permits self-service stations to operate in the state for the first time since 1949, Bloomberg reported. If price savings on self-serve are passed down to consumers, Corzine said at a news conference this week, the expected savings are 5 to 6 cents a gallon. The governor's plan calls for all or some of the stations along the New Jersey Turnpike to be converted to self-service. The busiest highway in the U.S., the New Jersey Turnpike stretches 148 miles.
