There isn't any malice in my post. But I inferred rhetoric and emotion in yours by the number of expletives / euphemisms. I can't possibly construe your post (or this reply) in any fashion that isn't snarky, at the very least. I urge you to read the guidelines:
http://ycombinator.com/newsguidelines.htmlYou definitely imply (both in your original post, and in this one) that every Prius owner is buying a new Prius every few years. That is a logical fallacy, in a variety of ways -- both that it is fact, and that it is necessarily bad. Even if that is the case, then that means there is bound to be a very good supply of cheap Prius cars available for the secondary market. Hooray.
The true fact of the matter is that producing cars (or trucks) is bad for the environment. A Prius may be bad in different ways than a Ford, but tearing up the Earth to produce an easier means of transport isn't eco-friendly.
