“Mats’s work was generally met with interest, but when he e-mailed the Oregon State Board of Examiners for Engineering and Land Surveying, things took an abrupt illegal U-turn. The Board told Mats it had no interest in hearing about his ideas. Fair enough. But the Board didn’t stop there. After a two-year investigation, it fined him $500 for publicly criticizing the timing of traffic lights without having a Professional Engineer license. The Board also forbid him from continuing to discuss his research.”
