The only reason it "works" for you is because of the huge rebates and other special deals. Taxpayers (a.k.a. my) money is subsidizing the whole deal. If they start charging what it really costs, things wouldn't look so rosy. Plus you live in CA where the weather is usually nice and sunny. Try it in the North East or Mid West, with snowstorms, and other crap weather 1/2 the year. I doubt if you'd be so enthusiastic.
