You shouldn't remove cats on a car for the very basic fact that when you do so, you will then be producing the equivalent pollution of 100 cars. Not only is it bad for the environment, but bad for health. You wouldn't throw garbage out your car window would you? Of course not. So why is it then OK to start spewing tons of untreated exhaust for the rest of us to breathe? Same thing. It's called being a good steward.

Actually it's "couldn't care less". And the pre-1975 cars that are "still on the road"? A tiny minority that is not going to impact the overall pollution level any significant amount.
