okay, so I'm still learning the emissions game here...the Civic Hybrid is cleaner in 4 or 5 states than the Prius (1 or 2). In the other 45 or 46 states the Prius is cleaner. And by how much in either case? Is it pretty significant between the tier 2 and tier 3 bin thing? Why can't Honda just put out a clean car for ALL states? Wouldn't it cost more to manufacture 2 different versions of the same clean car? Why the differing standards for an otherwise green car? Too many questions, I know, but I'm trying to formulate some understanding of the emissions thing...thanks.
