Car Pollution

[Sueven]

This is mostly directed to Fallanthas, who asked awhile ago if anyone had statistics on whether replacing old cars causes more pollution than it's worth (I think). I don't know an exact answer, but I did find this:

''Fifty percent of pollution comes from the oldest 10% of cars,'' he says. It's an argument often used in favor of proposals to get older models off the road.
