Actually they do.
Look into document titled "NOTICE OF INTENT TO ASSESS CIVIL PENALTY". It says just so:
"By reviewing, critiquing, and altering an engineering ITE formula, and submitting the critique and calculations for his modified version of the ITE formula to members of the public for consideration and modification of Beaverton, Oregon’s and “worldwide” traffic signals, which signals are public equipment, processes and works, Jarlstrom applied special knowledge of the mathematical, physical and engineering sciences to such creative work as investigation, evaluation and design in connection with public equipment and works. Jarlstrom thereby engaged in the practice of engineering…
…
By engaging the practice of engineering (specifically, traffic engineering) without registration, Jarlstrom violated ORS 672.020(1), 672.045(1) AND oar 820-010-07370(3)(c)
on a second occasion.
So his crime was not just in calling himself "engineer", but "reviewing, critiquing, and submitting the critique to members of the public".
Not to mention he attempted to "advise members of the public on the treatment of the functional characteristics of traffic signal timing" (from the same document)
It's more like you see bridge that is about to collapse but are gagged by local authority to prevent making your knowledge public without proper licence.
