General Motors unveiled an updated version of the Chevrolet Volt Monday at the Detroit auto show. Since its debut in late 2010, GM has sold 73,000 of the plug-in electric cars. California, which allows Volts in designated high-occupancy vehicle lanes with only the driver aboard, leads the way by far. Here are the top states and the percentage of Volt sales.
