Problem
Automobile emissions requirements are stricter in Japan than in the United States (where many areas have no vehicle inspection at all). In both countries, newer cars pass inspection (if required) easily, but older cars are more likely to fail the inspection and be removed from the operating car fleet. Draw hypothetical Salter graphs, with emissions on the y-axis, for the car fleets of Japan and the United States that reflect the stricter emissions standards in Japan. What happens to a late model year Toyota or Honda that has failed an emissions inspection in Japan and, therefore, cannot be used there? Google "Japan used engines" to find out. What effect does this have on the United States Salter graph that you drew above?
