The Zero Emissions Cars that are Illegal?

I found this article yesterday tucked in the car area at MSN. There are two things about this that bug me... First, you cannot buy one of these cars because it is illegal unless you live in a few select states. This just seems typical for the Bush Administration. The fact that I cannot buy a low pollution car in a place like Phoenix where we can see our air is beyond ridiculous.

Second, the writer of this article does not think that people would be willing to kick in an extra $100 for a zero emissions vehicle. If they can market undercoating that does nothing, surely car dealers can figure out how to market a zero emissions option that costs $100.
