Surely the people of Africa or Bangladesh are not so stupid as to not learn lessons from the US. We have better technology now, so they will use that in a lot of cases.
Don't get me wrong, there are cases where the old way is better because it is cheaper and so they will use that. However they won't use gas cars since we are developing battery cars, solar panels, and the like. Within a few years electric cars will be better for them as well.
