Having just spent some time in East Africa, I can say the air on any road was barely breathable. Many vehicles were very visibly spewing massive clouds of black smoke. I would not be surprised if this was largely due to lack of regulation/enforcement for vehicle emissions.

  When visiting India ~15 years ago, even mid-sized (for India, so ~1m people) cities were so polluted that the air was yellow. This was despite the fact that far fewer Indians own a car per capita than in the west- but the car they did own (and/or fuel they used) were horribly polluting.
