"When his wife got a traffic ticket, he tried to fight the system with science. It turned into a battle over free speech"

LAT:

using a stopwatch and two high-definition video cameras, Järlström ran his own tests on the intersection where his wife was ticketed. He said his findings showed that the intersection’s yellow lights ran on average 0.14 seconds, or 4%, shorter than advertised. He complained to the city.

...

But some of the biggest interest came from the Oregon State Board of Examiners for Engineering and Land Surveying, which regulates engineers in Oregon. After the board received an email from Järlström in 2015 presenting his idea, it launched an investigation — into Järlström.

On Nov. 1, 2016, the board sent him an civil notice finding that he was practicing engineering without a license and fined him $500.

“By asserting to a public body in correspondence that he is an (‘excellent’) engineer, and asserting to the public media in correspondence that he is a (‘Swedish’) engineer, Jarlstrom held himself out as, and implied that he is, an engineer,” the board wrote in its citation.
