This is an argument used to push those car crusher laws.  It is not always true.  If an old car is properly maintained, it is not as bad as claimed.  I once had a 73 Toyota that just before I junked it in 85, it went through inspection.  It passed the California pollution standards for 85.  The guys at rthe inspection were asking me how I did it because they couldn't believe it. (Neither could I for that matter.)
