Wow. I complain about paying $715 per year for two vehicles - my 06 Canyon and my wife's 10 Focus. Full coverage on both.
Winter 2011-2012 was warm, so average mileage only dropped to 30.1 MPG. Summer 2014 was not as warm as previous summers, but the addition of the vacuum gauge helped increase summer mileage to 38.2 MPG.
