I will say that my Camry gets an average of 29 mpg, thats not too bad.
I have lurked here and saw a few things that I got a kick out of. One was the gas mileage factor of riding a motorcycle. Yes: you can save a little gas on a motorcycle.Unfortunately that cost is offset by the cost of tires. If the bike has a chain you might think of buying a new chain every 12,000 miles,extra clothing, safety gear,freezing weather brings black ice (a killer) I have ridden home in a snow storm and believe it or not the trip wasnt so bad for my part ,You tend to drag your feet a lot. but if some else slides into you, you arent in a good defensive position. Motorcycles are a great hobby , but they arent very economical in the long run. Especially those that cost in the 20,000 or 30,000 dollar range.
States and Feds in their never-ending search for more money have just about driven cigarettes as high as they can get so they have to look on new sources. The carbon Credit scam looks to me like one of the sweetest scams to ever come down the pike.
You charge a tax on energy to pay to plant trees or do research on some Greenie inspired power source that doesnt exist and probably will never work, or some such horsecrap like that ,the government or Al Gore take the middle mans cut and a pittance will actually do some small amount of good that is all out of proportion to the money stolen. What a racket.
