Plus if you trade in one functional old car for a newer model with better emmissions, that perfectly good car is not magically lifted into automobile heaven never to emit again. It will be bought on the used market by someone else can't afford a new car (much less a $70K Tesla) and continue to emit whatever it emits today.
