"Tragic Capacity"
Copying a quote from a paper that has undergone Optical Character Recognition (OCR), I see that "traffic capacity" was translated as "tragic capacity". Sometimes the OCR knows best. So what happens when we systematically replace "traffic" with "tragic"? Typing "traffic" and each letter of the alphabet in turn, i.e. "traffic a", "traffic b" into the well-known Google search engine (logged in as me), I get the following interesting phrases, where I substitute "tragic" for "traffic", and they all still work.
