Never mind the automobile smoke. (Thankfully we dropped leaded gasoline but) have you ever found yourself following a vintage 1970's-era muscle car or similar down the road today?
Wow, that non-catalytically-converted smoke brings back the memories…
I spent two weeks in Caracas in 2000, and was shocked by the amount car exhaust. It probably wasn't excessive, but compared the US city I lived in it was always noticable.
