The exhaust used to be really nasty until just a little while ago. Nobody was focusing on the less harmful emissions.
Now we mostly fixed it, so it's time to look at the other stuff.

Basically, most of what you bought in 2005-2010, drove for a decade or more, and then sold for scrap eventually ends up in countries like mine. Moreover, most people take catalytic converters off their cars and sell them for $80-100 for platinum recycling. I think most "developing" countries have the same problem. So the world at large hasn't really solved it and won't solve it any time soon.
