#11 - Riding a motorcycle is cheaper.
My FZ regularly got about 30-34 MPG... but tires were more expensive, and needed to be replaced much more often than tires on the car... insurance was higher, associated gear is higher, chain replacements, sprocket replacements, etc.... It was easily as expensive as driving the car, if not a bit more.... coupled with the comfort issues and feasibility of making it a daily driver... with Givi 360's on the sides and top rack, I could do a small grocery store run, but it's no fun riding home with a gallon of milk, 12 pack, and a dozen eggs in the saddlebags..
